3g not working shouldn't be a FroYo issue, as mine works properly. Have you set up the APNs after the reset?
i reset them to default. Woke up this morning after having the phone off all day and it seems to be good now. very very weird.
Roze i have the tmo version hon
If it's not you...than it must be Mostly Harmless that has the AT&T version then 
3g work so well now. Even with zero bars pages loads up quick! Just glad your shit is working now.
