SD Card Questions!!


I am switching to a D2 next week and have some questions about the switch concerning my SD card. I currently have a Droid 1 that was rooted and then unrooted to send back due to warranty reasons. I am wondering what action i need to take to prepare my original SD card? I plan to root my D2, should i remove the update zip file that i put on it to root my original D1? Thanks.
