I installed the latest 1.20 GSM update on my unlocked Treo 650 (now Firmware 1.71) and find that, once every few days, the phone hangs up, often on the Calendar screen. Other than Snappermail and Volume Care, no other applications.

Any ideas? Do we need to update either of these packages? Using VC 5.20 and Snappermail

Thanks in advance for any help. All was fine before the update...
