Hello everyone. I followed the guide to jailbreak my iphone 3g with the 3.0 os. Everything has gone smooth. But now im just having trouble finding and connecting to my t mobile network . All i get is the no sim messages. Ive disabled 3g in settings, and ive installed ultrasn0w to no avail. I do use the gevey turbo sim card . It was working fine on firmware 2.2.1 but dont know what i may or may not be doing. Please any help will be gladly appreciated. Ive looked in the forums and havent found any answer to this problem.
