I've been successeded in upgrading my Apache (thanks to Nehemoth, Helmi_c and the team for the kitchen). And no problem with synchronizaton too. The problem is, I can't use my Apache for communication (outgoing call, receiving call or sms). FYI, my 6700 is RUIM enabled, and I'm in Indonesia. Is there any setting I must do related to the carrier, since I can use my 6700 for doing call before upgrading? Please help me...
