Does this apply to the Iphone 3gs also?
My coworker does this with his 3GS and iPad 1 now. He used the iPad microsim as a guide to cut his 3GS sim to the same size and contact alignment. Uses that cut out sim from the 3GS in his iPad. When he wants to go back to the phone, he just puts the cut sim back into it's outer portion, puts a bit of tape on the back of it, and voila.
