anyone try this yet? I know it fixes the bluetooth problem and thats what I was holding out for. Wondering what other bugs are present. Before anyone replies with their stuck up attitude of "its a beta dont use it" I used every single 4.2. ipad beta. I know there are bugs but it was still completely useable its all about figuring out what bugs are present and if those bugs will be deal breakers for you. which is the purpose of my post. what bugs are left in beta 5?
