Hi, i'm writing on my iPhone right now so sorry if spelling's a bit weird.

Home button problem on iPhone?

Is the LifeProof iPhone case worth the price?

I'm getting an iPhone 4S soon, and I want to get a case to protect it from everyday life. I've been looking into the LifeProof case ($79.99).It looks really great, being shockproof, waterproof, snow-proof, and dirt-proof. But is it worth the price of $80?

How to check if iPhone is stolen?

Okay, here's the deal. I'm interested on an iPhone 4s that I saw on craigslist. The person says that it isn't active but it is locked with Sprint.

The thing is that although he wrote that the phone is locked and not in use, it could be locked, but stolen, rendering it a useless iPod like phone. Now, is there a way I can know if this phone is stolen?

Is there a unique ID that the phone has that I can use to contact Sprint to find out if I can actually register the phone as mine?

New iPhone is completely dead! (isn't the charger) . - 1

I've been So unfortunate lately. Got a 2nd hand iPhone 3G off ebay last month… Worked for a few weeks then went dead and wouldn't charge. Took it to Apple and they said the battery was completely lifeless so they gave me a new one for £55. Took this phone home, worked for a day, when I woke up in the morning after it had been charging it was completely dead and wouldn't charge. Have tried everything. Have tried restarting it holding both buttons, have bought a new usb cable, i'm losing my patience now. It's a brand new phone! I don't understand it.
What can I do?

Problems sending SMS using iPhone?

Have a question for iphone. Have any of you encountered the same SMS being sent multiple times to the same number (at the exact same time)? The recipient only received the msg once but when the bill comes, I'm charged for the same message about 4 times as their records show the message has been sent four times.

Jailbroken iPhone 4s lock screen reading Null?

I was wondering if anyone can help me out here. I've been running the typophone 4 lock screen on my phone for a while and really like it; but one day I decided just to try a different lockscreen theme. I downloaded and tried the Android LS (That's "tap to unlock" instead of "Slide to unlock). But when I installed it, it was still running the slide to unlock text except now the text is saying "Null" and I can't get it to go away even with the "Slide to unlock Killer" mod. What can I do? Even with my lockscreen back to typophone 4, it still has the "Null" text sitting on top of the unlock text of the lockscreen theme. It also does the same when I switch back to the default lockscreen. It reads "Null" instead of "Slide to unlock"… It looks terrible! Is there any way that I can fix this?

I hope I explained this clearly, sorry for grammar. I typed this in haste.
Any help would be greatly appreciated.
