After reading all of the silly posts back and forth about the leaked beta, I decided to try it for myself. Its too early to say everything works great, however, I am not having any of the described issues. A few apps would not install, and a TON of apps that wouldn't install in 1.1.1 for me install fine now. The OS seems extremely smooth now, and the web browser is working really well. Additionally I installed the enhanced kernel, and OC is killing. This is the first time I feel like the device is actually performing the way it was meant to be. To anyone trying this, I wish you as much success as I've had so far. To those of you who aren't, I hope the final PR1.2 is released soon.
