loosing signal and reconnecting to t-mobile after updating to 2.0 and 2.0.1

[yehudah72]

now that i updated to 2.0.1 (and also with the 2.0 update), my iPhone looses Signal and reconnects to t-mobile very often (which is very annoying)... it didn't do that when i was Pwned with 1.0.2 (i know that's ancient firmware, LOL).

anyone else???
