New to android. need minor help, thanks

[insomniac]

Took my phone in today because it was stuck on first boot screen and wouldnt boot up and was having charging issues. They reloaded the software onto it and when it was handed back to me, advanced task manager had already been placed on there. Still like task management on the tp2 and palm pre better though. Every os has something that I like a lot and something that annoys me, can one of these giant companies get it right with all money they have, lol. I would have kept the palm pre if that keyboard was useable, actually that web os was the best I have used.
