I have a Treo 600 (Unlocked) with a AT&T sim card. It works with Cinglur and At&T network.

Lately, I am experiencing static noise complains from people that I am talking to at other end of their phones. The static noise goes in and out during the phone calls. It happens probably 5 out of 10 calls.

Also, my battery only last half day with normal phone calls now. Does weak battery cause the static noise.

Thank you very much for your time.

firmware: 03.05
Software Treo 600-1.13-AWS
