I recently purchased a rooted and unlocked SGS2. Coming from a Jailbroken iPhone4, this is my first Android. For more than a month everything worked great with my Fido sim. However, all of a sudden I lost data connectivity. After reading forums and researching on Google I reinstalled/flashed the firmware, modem and so on. But the problem still persists. In fact now my sim is not even recognised.
Did a clean wipe and re-rooted using Odin3 v1.85
Then performed a sim unlock using an app from Market.
Under 'About phone' the 'Baseband version' still say 'Unknown'
I don't know what else to do. Please help... Thank you
