Help Downgrading from 3.0! Please help!

[nremondelli]

So I tried to downgrade to 2.2.1 using the Gizmodo guise. I was able to successfully get it up and running, but I have no wireless at all. No At&T no bars, no Edge etc. Nada.

Any help is truly appreciated.

Also, now that it is jailbroken, is here a way to put the ligit copy of 2.2.1 back on?
