is the touch pro 2 the only phone that is going to have this sim slot?.....i have become so acustom to it.....it really saves time when transfering contacts and saving important txt msgs when u switch roms or hard reset.......i think they should come on all models of sprint phones.....will it cost alot just to have the sim slot in there for contacts ect and not a world phone since i heard that cost extra to do?........................what will you do with your sim cards when you upgrade to another phone?
