Yesterday I picked up another VZW BB 8830. This will be my third try. I't didn't have the latest update so I updated it. It still did the data loss thing all night long. I forwarded my messages to both my VZW and ATT BB's .net account. The VZW BB seems to fall asleep at times. Messages to the ATT BB always come in fine. Then the VZW BB "wakes" and several messages come in at once sometings after 30-40 mins being the longest. VZW users getting messages on BES or direct BIS (vzw.blackberry.net) check the message headers and look for time message was sent. Then compare time received. It should be no more than 2 mins difference. Spoke to RIM tech support on this months ago. They felt it was the VZW network. If you do a "reconcile now" it goes and get the messages after it does some 1XEV to 1x jumping. I've now returned the third VZW BB 8830. Just an FYI. VZW thinks I'm crazy. Signal here is -80db on VZ and -93db on ATT.
