I experience a strange problem right now .. I have both running 1.1.4 and 2.0 and 2.0.1 right now and everything has just always worked perfectly.
Just suddenly in the day it wrote No Service… and I have talked in it earlyer today, but now its only showing No Service.
I really just tried everything, reset the network, reflash it with 1.1.4, 2.0 and 2.01 repeatedly and tried with other simcards etc.. There is just nothing that works ..

Could really use some useful tips ..
I have searched around in the forums, but i couldn't find something useful.
iPhonen is a 2G 16 GB with 2.0.1 Jailbreake + Unlock Firmware .. always run perfectly.

(Sorry bad english)
