There is a similar thread, but the one question that I was interested in wasn't answered. If I upgrade to 3.1.2 on my 2g ipt and do not like it, can I downgrade back to the 2.1.2? The reason I ask is that I know a lot of people are stuck on 3.1.3 and itunes wont let you downgrade. I assume this is also true for ipt 2g users. Is it still possible to only upgrade ipt 2g to 3.1.2 if I have the firmware?
