Okay, sooo I decided 2 make anoter article cuz I found that my 1st 1 helped !! :)
This is an article on what 2 do if the apps on ur iPod touch wont open.
1st what u need 2 do is download an app, any app. Wait 4 it 2 load and install, then open that app. If its working, the other apps will automatically start 2 work also.
If u dont like the app that u downloaded, just delete it and the other apps will still work.
Unfortunatley, iPod Touch's have this problem and it will most likely happen 2 u if u have an iPod Touch.
The advice I gave should always work, it always works 4 me. Sorry if it doesnt work. If it doesnt, just search up something on Google.
Lemme know how this turns out :P
