Here's what I did:
I upgraded my virgin 1.0.2 to 1.1.1 without unlocking, then downgraded it to 1.0.2, then reflashed the Modem to 03.14.08_G, and applied anySIM 1.1. Then I upgraded to 1.1.1, and the infamous 0049 problem appeared.
So, which is responsible for this IMEI issue? The reflashing or the anySIM ?
