I have an i pod touch but none of the apps will open. i have tried reseting it and rebooting it but they still dont work

It's likely that the version of the Facebook app you are using is too new for your operating system. Try deleting it and reinstalling it.

try updating your I-pod on the iTunes software on your computer if that doesn't work back up your I-pod on the iTunes and then reset your I-pod to factory settings. now if you backed your I-pod up properly then log back into your I-pod with your iTunes account and plug it into your computer, it should automatically restore all your apps and music ect. then you should be able to sync what ever u want again the problembeing is u probanlypicked up a virus or something on your I-pod

1. Plug the iPod Touch into your computer.
   
2. Step 3 Power on the iPod Touch.
   
3. Step 4 Press the "Home" and "Sleep/Wake" buttons together for 5 seconds until the Apple logo appears.
   
4. Step 5 Release the "Sleep/Wake" button but continue holding down the "Home" button. The iPod Touch should reboot, and iTunes will notice the iPod Touch in recovery mode.
   
5. Select "Restore" and follow the instructions to finish restoring your iPod Touch.

try to find out the wi-fi password then just type it in when you go to the internet or app store and if u dont know wifi password then call your wireless settings it only works if u have wireless router

Try Reset

make sure you are signed out of the App store then go to settings, general, then scroll down to reset and hit "Reset All Settings"

give it a shot, it will not hurt anything

this usually the case with some high graphics apps, or poorly designed/ uploaded apps, you may want to consider leaving your ipod to charge for a while, or consider the apps you download, because they may not be compatible to an ipod, or your software. (If you haven't already, look for the new ipod touch software update, for $10.00) check this out:

This might also be caused from altering your factory settings, try restoring the ipod, again, (make sure to back up all your ipod files)
Hope I helped

Try rebooting your iPod touch by holding down both the sleep/wake and home buttons at the same time for 10 seconds. Should come back with an Apple logo.

The reason for this is that your iPod, like a computer, can start to run low on memory.

Another solution is, if you recently upgraded to OS 3.0, some applications might not be compatible yet. You can either wait for an update from the developer, or check if there's any current updates for the apps that don't open.

unfortunately, you're going to have to restore your ipod. just reinstall your apps. you could also try resetting it first.

Just hook it up to your computer and when itunes open,Click reset.

This will only work on the computer that the Ipod is setup on.
