ok so I tried this, and amazingly it didn't reset so I guess its not a device issue. Thing is now what do I do? If it is something backed up to my google account is there a way to delete whatever it is? Getting a new account isn't really an option.
Well... now comes the fun part. Troubleshoot your account at every step.
So...
1) Go to settings, accounts, add your Google account. Turn on wifi, walk away from access point, and see if the boot loop starts.
2) Go to settings accounts, add VZ Back up assistant. Turn on wifi, walk away form access point, and see if the boot loop starts.
3) If you haven't done so already, add your home access point. Turn on wifi, walk away form access point. See if the boot loop starts.
At each step, if you find that the boot loops begin, then you found your problem.
If you have no issues until now, then using your choice of Wifi/3g/4g, begin to reinstall all your apps form the market. FROM THE MARKET.
I noticed that all the Apps I had on my BIONIC, were not avaible on the NEXUS market. Which means that not all apps were compatible with the NEXUS.
But if I backed my phone up during activation, it installed everything.
So....
4) Install your apps 3-5 at a time (in batches) from the market. I had 75 apps. After each batch, walk away from the access point with the wifi turned on.
5) Keep doing this until you've reinstalled all your apps.
If the phone bootloops after a batch, you've found your problem in that batch of apps.
Uninstall and trouble shoot one at a time.
I bet that not all of your original apps will be available on the NEXUS market, or at least now you've installed the ICS version and not some old version stored on you Google account.
Let me know if this works for you.
I have a feeling that your phone will be back to normal here shortly.
