"Not ready for release."3.0 starson by ThatScienceGuy
Pros: The "Do not disturb" feature is great, as are incoming call options. I LOVE that they moved "Bluetooth." The panorama feature on the camera app is simple and intuitive. I like that you don't have to enter the iTunes password to download app updates.
Cons: The Maps App is so poorly designed that it's essentially worthless, and it's buggy too. iTunes and App Store are redesigned and not in a good way. Passbook seems completely broken.
Summary: Hold off if you can. In their haste to remove google from the devices, they've broken critical functionality:
The Maps app is garbage. It only displays a few street names at any given time, and they are not main thoroughfare streets, so it's hard to find landmarks. Traffic does not appear to work, even when displaying a Standard view map. When using turn by turn navigation it doesn't display street names in a way that's useful while driving. Often it doesn't show what street you're on. The Map crashes and just vanishes from the screen when using 3D view to scroll around San Francisco.
The iTunes and App Store apps act like a sluggish web app version of their original selves, sometimes updated apps don't go away after the update has completed.
Passbook doesn't appear to work. The only available action available is to go to the App Store, and when you do, it either crashes or you get a "Cannot connect to iTunes Store" error message even though the App Store loads.
Not yet ready for public consumption.
