I have an iphone 4s (which is awesome), but I also have a blackberry bold which has a different size sim slot. I would like to be able to pop the sim from my iphone 4s out and put it into the blackberry for times I don't want to risk my iphone (mountain biking, other higher risk opportunities to fall, etc.). Question. Does anyone know of or have any experience with a proper micro sim to sim converter that I could EASILY switch from one to the other? This would be an awesome thing to have the ability to do. Thanks guys!
