I have had the same issue when roaming in jamaica with my AT&T sim card.
Data works fine, but no voice. i have to manually switch to B-mobile (C&W) for both. The other interesting issue is it automatically "grabs" onto Digicel when I land in Kingston. No matter what, it does not pick up C&W.
I dont believe it is a 4.2 specific issue since I had the same issue when i was on 4.1. Someone in Digicel told me it was because the carrier cross-database registration (for voice roaming) was not working correctly. Curious to know if anyone else has had the same issue when roaming using AT&T.
9700 on 6.0.0.something, BES 4.1 on Exchange, BIS (AT&T)
Ex 8700, 8800, 8100, 8310, 9000
