BB 7230, spoke to Vodafone and got the unlock codes
Entered the codes and the unlock was successful... for a few minutes my sim was working on the phone was able to received messages.
All of a sudden the "Initialization Failed" started appearing.

Tried the following - Flash / upgrade

Upgrade to OS 4.0 - still the same error
Downgraded to Os 3.7 - Still the same error
used two different SIMS.
inserted a plastic between the sim and the clip so that the SIM presses harder no Luck.

Not sure what to do next.
Please advice
