Is your Apple iPhone suffering from poor battery life, a frozen touchscreen or an inability to connect to the internet? You're not alone, and we can help.
My iPhone's Home button doesn't work
The iPhone's Home button is necessary to reboot or reset the phone, both of which are quick and easy fixes to many iPhone issues. But what do you do when your iPhone's Home button doesn't work? Two common suggestions are to update the iOS software or to restore the iPhone through iTunes. If you restore, select the option to set the device up as a new iPhone, so that you don't restore problematic settings to the phone. (And be sure to sync first.) These fixes can resolve software glitches that may be causing your troubles, but an issue with the Home button could just as likely be the result of a hardware problem.
If you suspect that hardware is the culprit, and your phone is under warranty (or if you don't mind paying for a repair), take a trip to the Apple store, where they can help you determine the cause of the problem. They won't always fix it for you, however: I accidentally dropped an iPhone 3GS in water last year, and although the phone eventually dried out and worked again, the Home button never recovered from taking a swim. Apple doesn't cover water damage (and the iPhone has a liquid indicator inside of it, so the techs can tell if it has taken a dunk). The company wouldn't fix my phone.
If you're particularly adventuresome, you can try to disassemble your iPhone and install a new Home button yourself. Your phone also may need a new connector to the Home button. You can find people who sell the buttons and cables online, but this is not a project for the timid. Cracking open your iPhone can ruin it, and even if it does survive, you will have voided any warranty you may have had. Then again, an iPhone without a Home button is fairly worthless, so what do you have to lose?
My iPhone's touchscreen is frozen
If your iPhone's touchscreen isn't responding, turn the phone off and then back on. If that doesn't work, reset it. I know you've heard this before (especially if you've read this whole article so far), but these two steps really can solve a host of iPhone problems. If they don't correct your problem, you'll want to update the iOS software in iTunes, and then you can try restoring the phone in iTunes; select the option to set the device up as a new iPhone so that you don't restore bad settings to the phone, and remember to sync first.
If the screen still isn't working, the problem may be with the hardware, not the iPhone's software. If you dropped your iPhone, the connector inside may need to be repaired or re-seated. You can find directions on how to do that online, but be warned that the procedure requires you to open up your iPhone and dig around inside. If your iPhone is under warranty, you're certainly better off taking it to an Apple store instead.
If the connector isn't the problem, the screen itself could be dead. You can order a new iPhone screen and replace it yourself following instructions from sites such as iFixit.com. And remember what I said about the warranty? That applies here, too.
