Ok, so after hearing all of the new stuff in iPhone 3.0, I had to test it out. I joined the iPhone dev program (which I was planning on doing this month anyway) and downloaded and installed the iPhone 3.0 beta to my iPhone. I played with some of the new features and then loaded up all of my programs. I then attempted to setup my work Exchange account. I say attempted, because it never worked. It would never get me to the step to input my actual server address. Then I started trying to use some of my clutch programs only to notice extreme lag and some quirky issues. Using the Facebook application, it would load all of the text and menus, but would not load the pictures for any of my friends. Tweetie would sometimes not load all of the avatars. Evernote just seemed to drag. None of these are issues with the programs or the developers…it is a beta OS. This stuff is to be expected which is why there are warnings all over the place when you download the 3.0 beta that you will not be able to downgrade back.
Of course, that is not true. Leave it up to the wonderful mobile community to figure out that you can downgrade back to the 2.2.1 firmware, but the baseband would stay the same on the iPhone 3G. Not a big deal. You get an error in iTunes after the restore, but QuickPwn will get you out of that issue. I followed the steps over at Gizmodo, but I was still having issues. I have not had my iPhone jailbroken for a long time and I really have no desire to do it now, but if that was the only way to go back to 2.2.1, then I can accept it.
