Got a GN on launch day and haven't really had any problems until this week. Started getting severe data drop, so I called VZW tech support. (ie. loose all signal and bars bounce from blue to grey constantly). The first rep. told me to turn wifi off and it would fix my problems.... Of course that didn't do anything. Second call in yesterday and case was elevated to level 2 tech. Rep confirmed no network issues in the area and said since it was happening in multiple places it must be the phone. Rep indicated VZW will overnight a replacement. Received alternate phone today. Questions: it is a certified like new replacement. Is it better to keep the replacement or my original phone? the original phone has a code 11.11 under the battery. Replacement has 11.12. Is there a new batch of phones released? Found it interesting that the rep was so quick to offer a replacement phone, but she indicated there were no known issues with this phone..... interesting!
