I’ve personally never felt the need for more than one cell phone number, let alone 3! But if your the kind of person who likes to keep business, pleasure and …more pleasure? strictly separate this little sim card ‘piggy back’ for the iPhone 4 has to go on your Christmas list!
The add on lets your fit a micro SIM in to the original SIM slot with a ribbon connecting 2 extra regular SIM cards. As you can see from the images here the iPhone sees all 3 SIM’s, but we’re not sure if this is by default or whether a Jailbreak is needed for it to work.
The whole kit and caboodle sit in a rather tacky looking clear plastic case.
