1st beta sucked balls and was barely usable. The second beta was actually usable. Third beta sucked again. 4th beta also sucks. At this pace they will deliver a pice of crap in June. Why can't you force quit apps? Seriously. WTF. Buggiest software with no way to kill the app. Brilliant. It used to work if you held the home button. Now I have to reboot every time the dialer app loses it's fraking dial button. Brilliant!
