The phone volume was low, regardless of the firmware version. Using a BlueTooth headset made it a lot more useable, but this phone isn't good enough in other respects to justiy that requirement. Data entry sucks. Most web browsing renders sites too small to be really useful. The Outlook integration is terrific, but without fast entry, sending email or typing documents is tedious. With shiesty audio volume, the PDA aspects of the phone seem even worse.
