Hello, I could not wait for my new sim card to arrive so I had the iPhone upgraded from 5.1 to 5.1.1, unlocked and jailbroken untethered with redsn0w 0.9.11b4 and with ultrasn0w. Subsequently, loaded it with a bunch of apps ad photos while waiting for post. However, today my sim card is here and I ve been having the NO SERVICE sign after I insert the pin code. I am rather a beginner here and have been simply following forum threads to perform the steps above. Therefore I would appreciate any helpful info. Few hours of googling did not help so far. Thank you in advance. e.
