Before I activated my RAZR MAXX I installed the Micro SD from my Thunderbolt (32gb). When I activated the phone it created a new partition. I want to get rid of the partition and just use the Thunderbolt card. What's the best way to achieve this? I also need to do a factory reboot for other reasons, so I'm looking for a way to wipe, the SD card, reactivate, and copy the backed up contents from the SD card back onto it.
