When 3.0 arrived I waited for an update until I upgraded. Now, with 3.1 I'm having the wifi problems so widely reported here. I'm trying to roll back to 2.2.1, which I have downloaded. So far 3 attempts have failed. I can only restore to the 3.1 Is it possible to go back to 2.2.1, and enjoy my touch as it's meant to be, or am I stuck with 3.1, and maybe someday a fix will be available?
