Today i unlocked my iphone 3GS, the wifi wasn't detecting any wireless network. Even the signal started to drop so i had to disabled the 3G. After that it worked perfectly. I hope the dev-team will soon figure out this problem so we can use the 3G service again.

Per Dev Team:

Those installing ultrasn0w will probably also need to do a single run of Settings->General->Reset->Reset Network Settings. We’re testing various fixes for that particular glitch.
