You can restore your iPhone if you don't know the passcode this can be done by :

  1. While your iPhone is turned on connect it to iTunes via USB cable
  2. Once iTunes has recognised the iPhone turn your iPhone off and DO NOT disconnect it.
  3. Turn your iPhone on while pressing the home key
  4. When the Apple Logo appears let go of the power key but keep pressing the home key until the screen goes blank
  5. This will put your iPhone in recovery mode and your PC will recognise it as "iPhone DFU mode"
  6. Once this happens go back to iTunes and you will have the option of restoring your iPhone.

Forgot my password for my iphone 4s


What can you do to bypass and reset a forgotten passcode on an iPod touch, iPhone, or iPad? You can't recover your passcode. Good news is that you may be able to reset the passcode by restoring the device.
A) Previously synced your iPhone/iPad with iTunes? If yes, then try the following:
  1. Connect your device to your computer that you normally sync it to, and thus contains the backup files.
  2. Launch iTunes.
  3. Select Back up by right-clicking (or Control-clicking) the device.
  4. After Back up is completed, select Restore and then restore from your most recent backup.
If iTunes prompts you to enter the passcode when you connect to your computer (*), or if the above does not work, try the following option.
B) If you did not previously sync your iPhone/iPad with iTunes, then try following:
You need to force the phone into recovery mode and restore it as a new device to remove the passcode. To do this:
  1. Disconnect your device (iPhone, iPad, or iPod touch), but leave the USB cable connected to your computer.
  2. Turn off your device by pressing and holding the Sleep/Wake button for a few seconds.
  3. Launch iTunes.
  4. Press & hold the home button while reconnecting the USB cable to your device. Continue holding the home button until you see "Connect to iTunes" on the screen; this will also cause the iPhone to turn on.
  5. You should see the "recovery mode" alert:
"iTunes has detected an iPhone (or iPad) in recovery mode. You must restore this iPad (or iPhone) before it can be used with iTunes."
Now that your device is in recovery mode, you must restore the device. You may either restore it to a previous point, or set it up as a new phone. This will wipe all files and settings, including the passcode. If you see a message stating that your phone is locked (*) and you need to enter your passcode, just ignore and close this message.
Note: Make sure that you are using the latest version of Itunes before attempting this.
(*) Passcode error message: iTunes could not connect to the iPad/iPhone because it is locked with a passcode. You must enter your passcode on the iPad/iPhone before it can be used with iTunes

Forgot my passcode


Bad News... you may have to Restore from iTunes. Here is some info from the users manual:
Passcode Lock By default, iPhone doesn’t require you to enter a passcode to unlock it. Set a passcode: Choose General > Passcode Lock and enter a 4-digit passcode, then enter the passcode again to verify it. iPhone then requires you to enter the passcode to unlock it or to display the passcode lock settings.
Turn passcode lock off: Choose General > Passcode Lock, enter your passcode, and tap Turn Passcode Off, then enter your passcode again. Change the passcode: Choose General > Passcode Lock, enter your passcode, and tap Change Passcode. Enter your passcode again, then enter and reenter your new passcode.
If you forget your passcode, you must restore the iPhone software. See “Updating and Restoring iPhone Software” on page 204.
Set how long before your passcode is required: Choose General > Passcode Lock and enter your passcode. Tap Require Passcode, then select how long iPhone can be idle before you need to enter a passcode to unlock it.

Ipod disabled connect to itunes


If you repeatedly enter the wrong passcode, iPhone or iPod touch will be disabled for longer intervals, before you can try again. After too many unsuccessful attempts, you won't be able to try again until you connect to the computer you normally sync with. Note that starting with iPhone 2.1 software, there is a setting to cause the device to erase itself after 10 consecutive incorrect password attempts. This setting is off by default. It can be turned on by tapping Settings > General > Passcode Lock after you enter a correct passcode.
If you cannot remember the passcode, you will need to restore your device on the computer that was used to originally sync the iPhone or iPod touch so that you can reset your passcode and resync the data from the device (or restore from a backup). If you restore on a different computer that was never synced to the iPhone or iPod touch, you will be able to unlock the device for use and remove the passcode but your data will not be present.
