Thanks - glad the new version is working better. We've squashed a large number of bugs.
1. The map screen will swipe but due to the map extending to the sides of the screen, a bezel swipe is required to switch to tabs adjacent to the map tab. This was recommended to us by Google employees on the Android team, so I imagine it's relatively standard practice.
2. We'll take a look at this. When you look into the different types of contract and pre-paid plans out there the functionality and settings rapidly became very complex. Once we get a bit more feedback from users we'll do some work to simplify them.
