I have a 3rd gen and i have checked it 3 or 4 times to make sure. I've been trying to update it but it wont, can anyone please tell me why?
Because you very likely really have a 2G iPod. Thosecan only go to 4.2.1. If your is 8 or 16 GB it is an 2G iPod. Apple only made 32 and 64 GB 3G iPOds. A 32 GB one can be either. To identify:
