Jake, first off welcome! and Yes Android is light years ahead of BB. My advice to you is to start buying your music from Amazon MP3, seriously your music will go with you no matter what! Secondly download Zedge, its a must have for Wallpapers and Ringtones!!! and lastly, dont download any task killers!!!! Your Evo is smart and powerful enough to do this on its own!!! Enjoy!
Oh and also always, always, always save your contacts to Google!!! incase you lose your phone you will always have your contatcs info!!! ( via Gmail )
