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 won't connect to the internet
If your iPhone is failing to connect to the internet via your data network, try resetting the phone. Press and hold both the Home button and the Sleep/Wake button at the same time, and hold them past when you see the 'slide to power off' option. After that disappears, you'll see the silver Apple icon, and your phone will start up again.
If that doesn't solve the connection issue, try resetting the iPhone's network settings. Go to Settings, General, Reset, and then select Reset Network Settings. Note that you may need to re-enter any network passwords you had saved in the phone. If that still doesn't correct your problem, you may need to contact your mobile network. The folks there may need to reset your internet capability from their end.
My iPhone won't connect to Wi-Fi
If your iPhone is connecting to your cellular data network but not to any Wi-Fi networks, you can try resetting the phone and its network settings, as described above. You also can try connecting the iPhone to iTunes and updating the software, or restoring the phone.
If your iPhone is having trouble connecting to one specific Wi-Fi network, try forcing the phone to 'forget' that specific network. Go to Settings, Wi-Fi. Touch the right-pointing arrow next to the network name, and on the next screen choose Forget this Network.
Then, reset the phone, find the network again, and add it back. While you're at it, confirm that you've entered the right Wi-Fi password, and reset your wireless router if necessary.
Some users have reported that the iPhone's Bluetooth capability interferes with the Wi-Fi radio, so turn off Bluetooth to see if that fixes the problem. If nothing else works, take your iPhone to an Apple store for repair: Its Wi-Fi antenna could be failing.
My iPhone camera doesn't work
This complaint seems to come mostly from users of the iPhone 4, who have reported problems with both the front- and rear-facing cameras on their handsets.
Apple offers a couple of suggestions for resolving the problem. First, it says to verify that you have not turned on any restrictions. You can find restrictions by going to Settings, General, Restrictions. Once there, make sure that the Allow Camera option is set to On. You also can tap Disable Restrictions.
Additionally, Apple suggests turning the phone on and off; if that doesn't work, try resetting (hold the Home and Sleep/Wake buttons until you see the silver Apple icon, and then let the phone restart). Other suggested fixes include updating the iOS software and restoring the iPhone via iTunes. If you choose the latter, remember to select the option to set the device up as a new iPhone so that you don't restore troublesome settings to the phone. (And remember to sync before you do this, as music, movies, and apps on the phone will be erased.)
If none of those fixes work, you may have to take the iPhone to an Apple store for repair. Users have generally reported success when they've done this.
