I recently wiped my handheld and installed the latest sofware with awesome results. Interestingly, I have a recurring problem with not being able to call out. At times, I will go to dial a call, it sets up, and it instantly gives the chime sound like I dialed the wrong number and displays the call log screen. The only way I can get it back in order is to pull the battery, not even a full power off helps. Any other experiences? TIA!!
