Great job on picking one of the best if not the best phone out.
there are soo many apps you can get over 400,000...
plus since you are running android you can even get the paid apps for free!(if you know what sites to download them from)
some of my favorite apps are Mytubo(excellent for quick picture edit),alarm clock plus,angry birds,uber music player,co pilot live(got it for free I can use my phone as a gps without data),Death worm, color note,ebuddy,Shazam and where's my droid..if you misplace your phone text lost..and your phone will ring even if it is on silent..text lost GPS..and it will send you the gps co-ordinates and a map of where your phone is...oh yeah and skype
