I jailbroke the iPhone using the Pwnage tool. I am currently running firmware 3.1.3. In Cydia, I installed bootneuter to unlock the phone. However, when I run bootneuter to unlock the phone, each time I place my SIM card from my 3G to the 4GB iPhone, the phone still prompts me to connect the phone to iTunes for activation (however, I get a signal from AT&T in the upper left hand corner). Am I missing something here? I am following the guide provided here http://customizeiphone.blogspot.com/2010/03/312313-iphone-2g-unlock-using.html Any suggestions/tips that I would need to do to get the 4GB iPhone to work with my 3G SIM? Thanks in advance!
