Reset and Restore iPhone to Original Default Factory Settings with Recovery Mode iPhone display freezing? iPhone doesn’t detect by or appear in iTunes? iPhone cannot sync with iTunes on PC or Mac? Cannot make or receive calls, send or receive text messages, or access email or the web? Or worse, iPhone simply won’t turn on and does not respond to tap or button press? If the problem still persists after you have reseted the iPhone, or tried various iPhone troubleshooting, it may be worthwhile to invoke recovery mode to restore iPhone to default factory settings, the original state as when you first received and unwrapped the phone.

Restoration of iPhone to original factory defaults will likely to fix all problem, with the downside that all data and information stored on your phone will be lost. Normally iTunes will make a backup automatically when you connect and sync the iPhone with the program, however, it’s still a good recommendation to copy out and backup everything that you may need on the phone before proceed to restore the iPhone.
To restore iPhone and reset the phone to default factory settings, follow these steps:

1. Turn off iPhone - Hold down the Sleep/Wake button for a few seconds until the red slider appears, then slide the red slider. Ignore this step if your iPhone is already off.
2. Press and hold down the Home button for about 10 seconds until a yellow triangle with a text which says Please Connect to iTunes appears.
3. Plug the iPhone into Mac or Windows PC. Release the button if you haven’t.
4. Run and open iTunes if it’s not already opened yet.
5. iTunes will prompt a message that says iTunes has detected an iPhone in recovery mode. Click OK.
6. You will be taken to the iPhone pane. Then, click on Restore.
7. Wait for the full restoration process to complete, and the iPhone will be back to the original settings state as when it left the manufacturing factory, typically a working phone again if you face any problem, unless it’s hardware related

If it got wet, you can bring it to any Apple Store. Nine times out of ten they will replace it for $150 to $200 dollars. Unless they determine it is a manufacturers defect and you are still under warranty, then you want have to pay anything. they will usually just replace it for you.
Otherwise, you may have to pay up to $200 for a replacement.
Hope this helps...Let me know...
