I posted earlier that I was getting 1 - 2 reboots a day. As far as I know I have not had any in the last 3 or 4 days. It may or may not be related, but I was having trouble with Fancy Widget Pro on my home screen and the reboots have stopped since I uninstalled it???? I'm also experiencing the oposite of what a lot of others are saying. I was barely able to hang onto a 3g signal at my house (poor coverage here), but since the update I regurlary get 4g with 2 bars, again I don't know if its related to the update or not. Lastly, I saw on another forum that there would be an OTA update coming from VW in about 2 weeks, the speculation is that it is either GB, a fix for the rebooting issues, or something to extend battery life.
Note: I did not do a factory reset.
Regarding swapping out the phone, it may help or it may be worse, some are experiencing 4-5 reboots a day while others are getting none, and it will be a refurb, I called for my wifes TB 16 days after purchasing it, and the tech said he had no choice but to send out a refurb. On his suggestion, I went to the VW store and convinced the manager to swap it with a new one. (played stupid, insisted that I thought I had 30 days, not 14). The Manager was excellant and had no problem swapping out the phone.
