I installed the OTA to see what it was like and tried to sbf back to froyo. I eventually made it...I think. I had to do multiple wipes along the way. I ended up back at the OTA and that took a lot of wiping. I had to sbf 2 or 3 times to get back to stock froyo and then install the OTA. Once I did that I had to do a factory reset on the OTA to get it back working the way it was originally. I am not saying the path is not there, but I screwed around with my phone for hours to get it to work right. Just a heads up for those thinking of going to the OTA with the idea they can sbf back easily.
