I need to switch from my G2 to my Nexus S 4G for some work that I'm going to be doing that I'm going to get dirty. I had this phone before I switch to my G2. I went to activate it and long story short Sprint said my phone was deleted from their system because my phone has been unlock to be able to run on a different carrier. The most I've ever done was rooting it, and I'm the only one who's possession it's been in. Does anybody have any advice?
