pls help me. i have a qd w/ v 03.15 software. when i try to back up my phone's memory on the mmc, "App.closed AppArcServerThread" appears. when i press ok, back up process will finish successfully. after that however, phone navigation is so slow that i have to reboot the phone. i have a transcend 256 mmc, but i don't think the problem is there. any reply will be appreciated. thanks.
