Sim card from iphone 3g to iphone 3gs problem. Please help.
Hi everyone. I tried to find a section for snowbreeze but couldn't find it so I will post my situation here and I apologize if it is in the wrong section. A friend of mine has an iphone 3g that is working just fine on att with appropriate sim. He recently was given an iphone 3gs because his friend said he could not get it to work. I decided to do some research and had him give me the phone. I ran snowbreeze and found an ipsw for the 3gs that is 4.1. Snowbreeze did it's thing (i did simple install) and the phone works great after restoring in itunes the file snowbreeze made. When I gave my friend back the phone he said the sim from his original iphone 3g doesn't work. No sim error on the screen though. Is there something I did wrong and is this a fixable thing? I am very new to all of this so please be kind. I have a feeling there is an easy fix for this. Any ideas? Thanks in advance for all of your help everyone!
