I've been having the data drop issue like many others here. It took awhile to notice as I spend most of my time on wifi. I kicked the wifi habit and noticed my phone was dropping data constantly, especially when I was lost and in need of google maps, or trying to look at facebook. I called Vz tech support and the first tech sent me a new Thunderbolt. That helped for about 2 days. The next tech had me reset the APN. When that didn't cure it I was offered a Razr. I've been enjoying a constant data connection since Wednesday. It was a fun 499 days but it's time to move on.
For those still experiencing data drop, I recommend you stop wasting time looking for fixes and get Vz to offer you a different device.
