I recently bought a 6230 which has firmware version 04.44. I tried to use it with my ipaq 4150 to connect via BT&gprs to access my work related documents. I had a huge surprise when my new phone reset it itself. I used before that 6310, 8910 and there was no problem with the BT. Also I checked the BT status on my ipaq and it seams that before the 6230 resets the signal from bt is dropped to 0. Also I should mention that this behavior is shown only when a high amount of traffic passes through my phone. Please advise!
