Either you installed ultrasn0w and you havebaseband is in the 02 or 03

Setting-General-About to see your baseband.
Also try reinstall and reboot if you are using correct baseband

Your iphone imei maybe blocked and ur using it on the same carrier it was blocked from so its rejecting your phone. So it looks like its one of these problems

Unfortunately no my friend...
I got BB 01.59.00 on my German t-mobile locked iPhone. I tryed to reinstall ultrasn0w several times. Even an update from ultrasn0w 1.1-2 to 1.2 didn't change it.

And the iPhone IMEI is not blocked. It works great without ultrasn0w using a t-mobile simcard

I had a problem with one iPhone 3GS. Only way to fix it was restore the operating system, jailbreak and unlock again. Now it is fine. Also until did that seem having wifi on did reduce network drop.
