I've done a little research and if I'm not mistaken it is possible to use the iPhone 4 micro sim (with an adapter of course) on an Android phone. I also heard this has to be on an Android Dev Phone? and this is where my questions come in. Does it HAVE to be on a dev phone? or can I use any AT&T android phone? and if I can, what are the steps I need to take for it to take the iPhone 4 sim, if any?
