Hey guys, I've been offered an iphone 4, and as I seem to be liking my new macbook pro I thought why the hell not. Here's my problem though. At the moment I have a blackberry, and I'm on contract, so I need to use the same sim card, the sim card however is obviously a normal one, so how do I "transform" this into a micro simcard that the iphone 4 requires? Can I do it myself for instance? Has anyone else been in my situation?
