using yellowsn0w after pwnage tool on 3g
Hey guys, I have a 2.2 firmware phone with the latest 2.28 baseband. Tried using pwnage tool but after everything finishes and seems to work, I can't get any bars for service with my T-Mobile sim card. Carrier under settings shows (null)(null) and I cannot make calls.
I wanted to try yellowsn0w but wasn't sure if there was any prior things I needed to do before proceeding as I have an unlocked/activated phone via pwnage tool.
Any advice would be appreciated.
