I upgraded yesterday and I can say this is what the storm should have been new out of the box
Very fast all aspects of this device are 200% better
Note do a clean install do not backup or restore
1. wipe your device completley twice
2. Pull battery wait 5 to 10 minutes reinsert battery
3. Instal clean version if .122 no backup or restore this should give you a device just like you get out of the box
4. After install wipe your device again this will let .122 reinstall itself on the device
5. Setup as need go to host routing register on network
6. Resend service books
7. Verizon only dial *.228 when answers press 1 follow promps
8. Verizon only dial *.228 when answers press 2 follow promps

this is how i did my upgrade to me it is the only way to install new OS on anything clean clean clean that way you are getting what you installed not some possible corrupt bits left over or imported settings that may need to be different under this or any OS
