I want to use both but I'm not sure what to do. I know I need a sim adapter but not sure what to look for. It seems the one's I've found require you to cut your micro-sim and then put it in an adapter? Would the cut micro-sim go back into your iphone then or would it be too small? Also, would I lose any functionality on the android by doing this since ATT has me down as having an iPhone 4?
