I was upset that it wouldn't work on my 8320 from T-Mobile. The screen kept blanking out on me every 10 seconds and then would do a full reboot. I did the battery pull and must have reinstalled the OS 4 times with the same results. I narrowed it down to the wifi/radio. If I left those 2 off, it worked fine. but once I turned either one on, it turned into a very expensive paperweight. Oh well, I guess that's why it's beta. Just chaps my hide that other people are able to use it with no complications. My main need was so I could finally use all 8gb of my MicroSD card.
