HTC is working on a official patch to bring the unofficial patch people to the same version as the official... don't worry
2.2 VPN doesnt work and without root access OpenVPN cant be installed - So there really does need to be an official way to go back and a custom rom with root access is all I'll ever install again after this fiasco.
I'm sure the "corporate" goal is to stop roots, wifi tether, etc. but everything I'm trying to do is supposed to be supported and I'm getting quite upset over this bug in the upgrade with no option to remove. Reinstalling my old rom should have been trivial and under my control.
I'm currently escalated with Sprint over this VPN issue - They are responsive to the problem, but unfortunately no resolution is obvious. I'll update again, but it sounds like whatever they do will be "magic" at the repair center, not something I can do / share.
