I have been going through a number of test to identify the data dropping issues that a number of users have reported and I think I have identifed one possible solution that seems to be working for me, I have ran my device for almost a week like this and I havent had any buffing or connection lost issues and I figure this may be something worth sharing..
Goto Settings / Wireless Networks / Mobile Networks / System Select and change it from auto to Home Only and reboot. this seem to help a lot and I havent notice any issues, but keep in mind if you travel a lot you may have to switch to Auto tp get reception in some areas.
This was just a test and cant say it will work for everyone but it may be worth a try....
