flash back to 2.1 before i have the vz techs diagnose my phone over the phone ?
Yes! Flash it back. If the VZW tech, for whatever reason, goes in and looks at the firmware version, you will likely find yourself at risk of having your warranty voided. And once it's voided I don't think there's much chance of ever getting it restored on that phone.
What issue are you seeing? Maybe it's caused by 2.2?
