I let my (broken) phone do the Verizon radio update last night.
I then followed
this link and had a backup and was updated to 8107 in about 10 minutes this morning. From 7720 to 8107, downloaded the 7720->7740 and 7740->8107 cabs, 8107 English and Spanish cabs. I didn't have to do the steps 9 or 10 but worth checking on.
edit: and yes my phone is broken and my daily driver still--only portrait mode and no tilt functions in games. Still better than my OG Droid or any new phone I could get with my upgrade plus NE2. Cmon VZW give us more
