I have an iPhone 3GS new bootrom on 5.1.1. This phone was passed onto me from my dad who bought it and was LOCKED to ROGERS. I just downgraded to 5.13 baseband (the one that just got downgraded from 6.15) and did a fresh OS install while I was at it. At the setup screen I put in my dads old SIM card to get passed the activation screen. Then proceeded to back up my phone with iTunes to restore it to its original state and put my contacts and such back on. I put in my BELL SIM card and unlocked with with ultrasn0w. So my question to you is, am I officially activated since I put my dads SIM card in in the beginning, or am I hactivated?
