How to make your own iPad or iPhone 4 micro SIM

Apple iPad
The Apple iPad is released in the US this weekend

Despite the 3G version of the iPad being sold unlocked, both that and the iPhone 4 requires a whole new type of SIM card - the micro SIM.

Or does it? That's right, we've been trimming away the mystery of the new micro-SIM.

At first glance, the electronic contact area is no different to that of a conventional SIM, you know, the type that's small enough to fit into a tiny phone never mind the hulking iPad or iPhone 4.

As it turns out traditional SIMs measure 15 x 25mm and have that angled corner. The new micro-SIM is officially 12 x 15mm. That's effectively the size of just the normal SIM contact area.

Apple was just wanting to be clever or it just wanted everyone to be forced to buy new SIMs, either way it's a touch annoying, but with our mighty scissors we can cut them down to size and so can you. SIMples.
