Hi, I am still using a 2.2.1 firmware on my ipod touch 2g...i havent upgraded to 3 yet cause i got some questions about it. The most important query is this. IF i upgrade my ipod, my baseband will upgrade to the newer version and there is no turning back from that right ? Even if i want to downgrade to 2.2.1 after, my baseband will be stuck to the 3.0's baseband. Am i right ? If yes what are the ups and downs of that ? Thanks.
