To start, I'm not a dev, and my iPhone4 is my primary phone, and very important. The beta 1 release is overall very very reliable (at least it was for me) for a initial beta release. Of course iOS5 at this early stage has numerous glitches, but none that were detrimental to my use of the phone. The led notification, is a nice touch, but too bright imo (I'm almost positive iP5 will have it's own notification light). I'm completely happy with the new notifications, and the the drop down widget/notification center. Obviously wireless sync isn't working effectively yet, but you don't need to use it to know it's a welcome addition. I will however be reverting back to 4.3.3 for now, but for those on the fence, and are like me, impatient, I say try it. You can't access all the new features now, but the ones you can are nice, and it will get you used to what to expect at this point. I guess the point of me starting this thread, was to show those that aren't professionals like me, but can get on iOS5, and are on the fence, that imho it's worth a try. And it's not as bad as a lot of people are b1tching and making it out to be. As well all know, it is beta1. I'll go back at beta 2.
