Android Question

I have about a 2 month old NEW Motorola droid razr m..all of the sudden my homescreen went black and a screen that said 'amazon mp3 crash" came up and then all these little boxes for all my apps came up saying, "unfortunately homescreen has stopped" or for whatever apps I have. it wont let me do anything. ive tried turning the phone on and off and taking the sim card out. I will NEVER EVER have another piece of shit droid phone again.
