HELP PLEASE - Cannot make calls after unlocking XDA2

[Norman Fineman]

I have unlocked and XDA2 - Radio version 1.05.12 using the earlier system as the latest unlocker would not work.

Everything seems fine after entering the unlock code & with a Vodafone sim in place the signal strength is fine but when a call is made the call seems to dial and immediately disconnect.

Any help gratefully received

Exactly same behavior on MDA3 from Cingular. Got the unlock code from Cingular. The code was accepted. Entered T-Mobile SIM but then phone will not make or receive calls. Even after putting original Cingular SIM it will not work.

Inserted another Cingular SIM and attempted call. It starts working. However, if I put T-Mobile SIM it would go back to same state.

Any help would be appreciated.

I have the same problem! :(
Please somebody, any ideas? I have a dead radio now.
