Ok so I my phone was stuck in the boot logo so I had to do something to fix it. I found a jailbreak using snowbreeze which doesn't change your modem firmware. I used this jailbreak and restored using this custom firmware. I am right now running on 3.1.3 with modem firmware: 05.11.07. I don't know how to unlock this phone!! I thought i just download ultrasnow in cydia but that didn't work. I am in need of help. If you know how to downgrade it then help me out too!! PLEASE!!!!!!
