DIY iPhone 4 microsim adapter
When you brought your sexy new iPhone 4 home, you might have also noticed that one of these adorable little microsim doodads came along for the ride. The cute little guy won't so much fit into your old phone.
Luckily, the array of contacts on the microsim are the same as those on the old school sim, they just live inside a smaller slab of plastic. You could buy a microsim adaptor online for about 10 bucks shipped, but in a pinch you can make your own adapter with heavy card stock, a razor blade and some patience. First, cut a piece of card stock to the shape of the old school sim. You can test fit it in the carrier of your old phone. It can move around a little, but should fit at least as well as your old sim card.
Then place your microsim on the card stock equidistant from the three sides that don't have that little notch. The line drawing below shows the proper location.
Cut around the microsim. Work slowly so you get a nice snug fit.
When you're finished, the sim adaptor should sit in the old carrier sort of like this. Make sure all of the little bits of card stock have been trimmed away so you don't gum up the works inside of your old phone.
Slide it into your old phone.
...and Robert is your father's brother. It doesn't have to be perfect. As you can see from the size of the six contacts on both the sim and the microsim pictures, there is plenty of room for error.
