on 12/24 i took the ota upgrade to jb it loaded without a problem. my phone (RAZR MAXX) was not rooted. I cannot use foxfii now, pdanet is working fine. I've read this forum and decided to talk to verizion. they claim this was an official upgrade and it is still under way, they can't or won't return my phone to ics
1. Glad to hear you didn't have problems installing the update.
2. At this time, Foxfi isn't compatible with Jelly Bean on the RAZR/RAZR Maxx. They mention that on their website:

3. Others have reported they were told by Verizon that the upgrade was pushed out accidentally, and was stopped as soon as they discovered that.
4. Once the phone is upgraded to JB, it cannot be reverted back to ICS. There are software / firmware changes that take place that cannot be reversed (it seems). Yor only hope would be for a warranty replacement of the phone.
