has anyone used both of these phones? i am considering leaving sprint and going with the droid x (since i'm officially addicted to a large screen). but my evo keeps dropping 3g service and i have to do battery pulls. i have taken the evo in for service and they claim to have "fixed" it, but it still drops 3g alot. is the droid x a good phone, or is the evo superior? i really like the evo, but it is just not being reliable anymore. thanks!
