So far so good. did a complete wipe of course. Flashed up 1.7. Everything worked except facebook for android threw me a error. After reboot, it let me log in but error out again. Oh well, could just be the facebook app. May try unistalling it and reinstalling from the market. will check back on that.
Gmail, exchange email/contacts, 4g, gps, weather, market all work. Thanks OMJ!
update: facebook worked after reinstalling from the market.
Update 2: no sense reboots yet
