When I spend about half a grand on a cell phone, I’m thinking . . . “i want to get my money’s worth!”

That’s how I feel, anyway — which is why I made it my business to put my new iPhone through the paces from jump street by scouring the web’s most serious iPhone resources for the most useful power tips/ tricks available. The result is this collection of 16 iPhone power tips that will help you get even more enjoyment out of your new favorite toy! Some of these, granted, you’ll need to Google to get the current URL. But, if you want, you can just click the link for the complete article with photos and videos.

1. Unstick a Stuck Slider: if you’re iPhone’s slider ever gets stuck — as in, it simply refuses to do anything when you try to slide it, usually because you want to make the iPhone up to use it — here is a fix from iPhone Atlas (www.iphoneatlas.com): press the Home button once before attempting to move the slider for the first time.

2. Make Skype calls: Up-front disclaimer: We’re not talking about free, voice-over-IP (VOiP) Skype calls here. We’re talking about making SkypeOut calls, which are not free but can drastically reduce the cost of making international calls on your iPhone. Matter of fact, SoonR lets you access Apple Mail files, mailboxes, and contacts. It also lets you grab documents from your Mac for viewing on iPhone, including PowerPoint presentations and all that kinda’ good stuff.

3. Know Where to Go for the 411: Lucky for you, the world has gone iPhone crazy. That means there a lot of excellent sources of info on the latest iPhone developments out there on the web. Bad news: there’s a lot of crap, also. Here’s a short list of our favorite iPhone info sites:

- modmyiPhone.com
- iPhoneFreak.com
- iPhoneAlley.com
- The Unofficial Apple Weblog’s iPhone page
- Gizmodo’s iPhone coverage
- iPhoneAtlas.com

While you’re checking these sites, keep in mind that some sites you might already be visiting on a regular basis have really done a super job of becoming iPhone-friendly, including Digg.com, Amazon.com, FaceBook.com, and Netvibes.com!

4. Play Great Games: You know what Jack says about all work and no play! Not that the web surfing you’re doing on your iPhone is all work-related, yeah right? Games — most of which are free — are starting to pop up for the iPhone, and we’re sure there will be more where those came from. For now, you can just launch the Safari browser when your iPhone and visit these hot game sites:

- MacMost’s collection of iPhone games, including classics like solitaire and minesweeper (free, MacMost iPhone Games).

- mynuMo has 4 iPhone games, including iWhack — a whack-a-mole knockoff where the mole’s replaced by a headshot of Microsoft’s Steve Ballmer — and Blackjack (also free, myNuMo iPhone Games).

- iGiki’s games, which include Hangman and Canyon Crawl — aren’t free, but then, they’re only a buck a pop and might be just what you need when you get tired of the freebies (99 cents per game pack for 99 days, iGiki Games).

- PopCap’s Bejeweled, (free, PopCap Bejeweled).

5. Beat a Shortcut to your Fave iPhone Apps: Handy iPhone apps, like Leaflets (free, Get Leaflets) and Applists (free, Get Applists) put most iPhone apps your fingertips, but if you want to build your own list, just collect the apps you tend to use the most into the same bookmarks folder in Safari on your computer. Then, the next time you sync your iPhone, using iTunes, be sure to check “Sync Safari Bookmarks” on the info tab, under Web browser.

6. Rehang the Wallpaper: If you’re up for a bit of iPhone hacking, you can take any image you find anywhere on the web and turn it into a custom wallpaper.

But there is a much easier way: Download a 320×480 pixel image for free from a variety of online sources, saving them all in the same folder on your Mac. In iTunes, with your iPhone docked, select your iPhone, click the Photos tab, select the radio button next to “Sync Photos From…,” then from the drop-down list, select “Choose Folder…”

Next, browse to the folder you just created, then click “Apply” in the lower-right hand corner. Finally, on your iPhone, go to Settings, Wallpaper, Photo Library to hang your new wallpaper!

7. Take Self-Portraits Because the iPhone camera shutter’s button is a “soft” (i.e., onscreen) button, it’s a bit tricky to take self-portraits with it since you have to turn the phone around so you can no longer see the button. Here’s the solution: with the camera feature selected, place your finger on the camera icon and turn the phone around so you’re facing the lens. Then, smile pretty and let go of the shutter button! You’ll hear the telltale “click” — and, you’ve just taken a self-portrait!

8. Reveal Secret Features: When Apple released the first firmware update for the iPhone on August 1, 2007, it did so with little fanfare, and attributed most of the updates to “security fixes.” The Wall Street Journal’s Walt Mossberg discovered a few new non-security-related features on his side phone after the update including:

- Greater capacity in the iPhone module’s Favorites list (used to be 20, is now 50).
- Ability to automatically blind carbon copy (BCC) yourself on all e-mails sent, where previously, your only option was to CC yourself, which alerted your recipients what you were up to…
- Compatibility with some car adapters and external speakers, originally created for the iPod. For more iPhone and tech tidbits, visit Walt’s blog.

9. Just Ditch the Camera Altogether: On the other hand, if you know you’ll never use the iPhone’s camera, you can just remove it altogether. (If you work for or with certain government agencies, you’re iPhone may actually be considered “contraband” on their property because they don’t want you taking secret photos of Bigfoot, Elvis, or (believe it or not) alien spaceships!

10. Get the Official Mod Tool: If you’ve already had to send your iPhone back to Apple for warranty repair or replacement, you may have already discovered something different about the replacement iPhone. First off, it comes in a much thinner box. Second, it comes complete with the “official iPhone SIM card removal tool”: a paperclip! Yup, Apple actually supplies a paperclip with all replacement iPhones, along with instructions for using it to open the SIM card slot and insert your card!

11. Buy Spare Parts: If you’re the type who simply can’t resist trying to take your iPhone apart, here’s where to go to find replacement parts when you go too far: iPhone Parts. Sources of mine told me that Apple charges $300 for a replacement screen, but you can get one from iFixIt for only $199.95.

12. Kill that Annoying GSM Buzz: If you hear a buzzing sound, while using an iPhone cassette adapter in your car stereo, such as Monsters iCarPlay — which claims to be iPhone-compatible (but doesn’t appear anywhere on Monster’s website) — Gizmodo offers a low-tech solution: aluminum foil… Yup, just take a little bit of Reynolds Wrap and wrap it around the cable closest to your iPhone. Doing so eliminates the need to switch to “Airplane mode,” which would be a viable solution if it didn’t send your incoming calls to voicemail!

13. Find Wi-Fi Hotspots in Your Neighborhood: JiWire makes it easy to find the nearest hotspot when your iPhone — so you can rescue yourself from the slow-moving hell that is AT&T’s EDGE data service. Surf on over to iphone.jiwire.com on your iPhone and fill in your location. If you’re a cheapskate (like me), check the box for “Search Free Hotspots Only.”

14. More Wi-Fi Performance Enhancements: Apple has a potentially useful collection of WiFi related iPhone tips in a regularly-updated knowledgebase article on its website. Suggestions include fixing problems like paid WiFi connections that drop off suddenly, weak WiFi signals, and WiFi connections that revert to EDGE due to issues with WEP passwords, or problems with Mac address filtering.

15. “Hack” Your iPhone!: Disclaimer: this tip isn’t for everybody. Some of these “hacks” (i.e., self-made modifications to the iPhone’s default behavior) are intended for people who have experience changing the way their computers behave by accessing the underlying code governing such behavior. You’ve been warned.

- For Macs: iFuntastic and Installer.app.
- For Windows: Installer.app or iBrickr.

Once you’ve installed one of the above helper apps, you can try an ever-expanding array of iPhone mods. With iFuntastic, for example, you can add your own custom ringtones, rearrange the Home screen, and change the AT&T logo. Installer.app goes even further, letting you install and play Nintendo games that feature tactile feedback! The good folks at Gizmodo.com make it easy for Mac users to take advantage of this newfound power over their iPhones with a handy tutorial (visit their site and search for install apps iPhone).

Windows users can also use a helper app called iBricker to modify their iPhone, install custom ringtones, and install third-party apps. But, if all you care about is adding custom ringtones, you might want to try Efiko’s iPhoneRingToneMaker ($10).

16. Just Don’t Be a Sucker!: While searching for the latest iPhone apps, you could run across some websites that’ll offer you instant access to hundreds of the latest apps — all for one-time membership fee of $49.95. These sites include, but are not limited to, www.iphonenova.com, www.iphonecyclone.com, and www.iphonedownloadpro.com. Problem here, is that these sites (IMHO) are scams.

I ponied up $50 for membership to iPhoneNova, for example, which claims to be the “World’s First iPhone Download Service.” Guess what it really is? It’s a BitTorrent-like site for downloading illegal content you can view on your iPhone or iPod.

But, your $50 membership only gets you a BitTorrent client called Tomato Torrent and links for you to download two more already-free apps that help you convert existing videos and ripped DVD content to be viewed on your iPod/ iPhone. You also get links to a mere five (5) web-based iPhone games and a huge, poorly-organized list of illegal movie downloads like “The Simpsons” and “Transformers.” Nuff said; as Napoleon Dynamite would say, “…What a Rip-off”!
