When your iPod Touch displays a message telling you to connect it to iTunes, it may be in recovery mode, or have been disconnected in the middle of an update.
To get rid of the screen, you must reset your device. If in passcode mode, an iPod Touch must be manually unlocked or fully restored to get back to the home screen.Forcing a Reboot
When your iPod Touch is stuck on a screen that is instructing you to connect with iTunes, a normal restart will probably not work, as the hard drive has become frozen.
You can still, however force the iPod to reboot using a process called resetting.
To reset an iPod Touch, hold down the "Sleep/Wake" and "Home" buttons at the same time until an Apple logo appears, indicating that the device is rebooting.
When an iPod Touch reboots, it always goes back to the lock screen. Passcode mode will still be enabled.

Unlocking With the Passcode
If you know the passcode for your iPod Touch, slide the "Slide to Unlock" arrow and then enter your code on the next screen.
Upon entering your password, you will be directed to the device's home screen. If you enter the wrong password too many times, it will become disabled temporarily.
The iPod Touch can also be set to erase all content after 10 incorrect passcode attempts if you previously enabled this feature, don't attempt more than 9 entries.


Unlocking Without Passcode If you have forgotten the passcode to your iPod Touch, the only way to unlock the device is by restoring it.
Restoring an iPod Touch returns it to the factory settings, meaning that any settings, applications or music you added to the iPod are removed.
Once the device is restored, you can re-add your downloads and other information using the backup copies in your computer iTunes program.
The passcode setting will be disabled unless you manually enable it again.

Consideration

If you don't have a backup of your music and applications in iTunes on your computer, you can also download another copy from the iTunes Store or App Store on your device after a restore.
Any photos that are deleted during restore, however, will be lost forever if a backup does not exist.
Always back up your information via sync on a regular basis to avoid this problem.

If you have forgotten iPhone passcode and it resulted in failure to unlock your iPhone. You can follow below steps to unlock it with iTunes or iCloud.

-Use iCloud

• (1). Open and log in iCloud on your laptop or PC that is connected with the iPod touch.
• (2). Click Find My iPod and let it start to search and connect with your iPod touch APP.
• (3). When iCloud is connected to the iOS device, its position will be fixed and shown on the map, then click the option at the upper right of Clear iPod and follow the next indication.

-Use recovery mode

• (1). If iTunes prompts you to enter the password, and you cannot remember it, try to use the recovery mode to unlock iPod touch without password. Given that you are using recovery mode, you are not able to backup before resetting device, which means that you are going to lose all the data on the iPod touch.
• (2). Close iPod device completely. Hold Power button and slide the Power Slider to close iPod touch.
• (3). Connect your iPod touch to the computer and use iTunes to enter into recovery mode.
• (4). Open iTunes and hold Power+Home buttons long before the logo of Apple appears. Then click Recovery Mode.
• (5). Click Set Up As New iPod Touch. Initialize the settings of your iPod touch and import the backup and restore the data.

I had the same problem with my iPod touch 3rd Generation, the slide bar will not slide to unlock. I could however use the slide to power off at the top of the screen. I tried everything from rebooting it to a full restore and nothing worked. I finally took the Touch Screen Glass Digitizer off and the ribbon cable that connects to the board had come loose. I pluged it back in and everything worked again.

This is the video tutorial that I used to jailbreak my iPod touch.

Basically, just follow the instructions. It worked great for me and I love all of the customization aspects of the unlock.

Try the following

Turn the ipod off and then on again.

If that does not work reset the ipod while it is connected to the power. You do this by pressing and holding the sleep/wake button and the home button at the same tme for at least 10 seconds, until either the apple logo or battery symbol appears. If the battery symbol appears, charge the ipod until it is fully charged.

Hope this helps.

Use the Five Rs to restore the iPod. You will lose the data that is currently on it if you restore but you can always re-sync the data to the iPod.

If you jailbreak (quickpwn.com) there is an app on cydia that will change it to tap to unlock rather than slide so it should be more sensitive.
