OP welcome to AF and welcome to Android. Hadron has gave you some great tips.
I would like to move this thread to a different forum for the actual device. In which you may get even more feedback. Which Sensation do you have? Sensation , Sensation XL, or Sensation XE?
I used to be Android all the way but bought an Iphone 5 in October. Feel free to ask me how it's going via PM.
GO BRONCOS AND ROLLLLLLL TIDE!!!
