I have forgotten my passcode. iPhones disabled but the laptop I sync with has water damage. Is there anyway to unlock

If you have forgotten the passcode on your iPhone, you will have to restore the device.

To restore your iPhone -- which, again, deletes all of your data (songs, photos, videos, apps, and so on) on the iPhone use the following directions. Be absolutely sure that you have backed up the content on your iPhone before restoring it.

If you have previously synchronized your iPhone with iTunes on a Mac or Windows computer, you typically still can backup recent additions to your iPhone by connecting it to the same computer you have used before without having to enter the passcode.

After the backup, you just need to "restore" your iPhone and have the backup copied onto the iPhone with iTunes.

Apple's official instructions to restore an iPhone with iTunes are:

1. Connect your iPhone to your computer [that you have previously used to sync the device].
2. In iTunes, select the iPhone in the "Devices" list, then "Summary" at the top of the screen.
3. If iTunes doesn't automatically synchronize your iPhone, do so manually [and confirm that the sync and backup were successful.]
4. Click “Check for Update.” iTunes tells you if there is a newer version of the iPhone software available.
5. Click Restore. Follow the onscreen instructions to complete the restore process. When restoring, it is recommended that you [again] backup the iPhone when prompted.
6. When iOS Setup Assistant asks to set up your iPhone, choose "Restore from iTunes backup."
7. Select your device in iTunes and choose the most recent backup of your iPhone.

After this process, your iPhone should be restored with the information from its last backup, but it no longer will have the passcode enabled. It would be wise to think carefully before setting another passcode or using the passcode feature again.
