Thanks for the report! Helps a lot.

reselecting cells isn't an error or unusual behaviour. In fact that's what the 
phone is supposed to do, as long as it's two BTS with same signal-level, and 
the phone doesn't *transmit* every time to re-associate to the network

Please see Wolfgang's mail about NDA. Cable probably needs another pinout for 
the 2.5mm jack, if anything.


cheers
