I restored my phone with an unactivated att sim card and used redsnow.. so i can get push notifications... ultrasnow worked fine with my tmobile sim. Now wifi takes a long time to pick up my router. It use to pick it up instantly. Now it doesnt even connect to it and its really annoying. Is anyone else having this problem? If i knew 3.0 was going to drain my battery,have no wifi, i would of never updated geez :-\
