Ok so Trying to download the free angry birds, which I used to have until I restored my ipod to clean it all out first time since I first got it. And lo and behold back to 3.1.3 which wont allow me to run free angry birds and various other apps. I could have sworn before that I had at leave ios 4.0. any insight would be helpful.
Googling shows that a model MA623LL is a first generation iPod and can only go as far as iOS 3.1. You can check Apple identification site (it doe not list model numbers) for how to identify models. http://support.apple.com/kb/HT1353#ipodtouch
