That's right. You don't have to spend hundreds of dollars to upgrade your iPhone 4 to the iPhone 4S. Just buy this special kit. It is just 99 cents! It's easy. Here's how:
1. Buy sticker.
2. Peel off sticker.
3. Apply sticker carefully to the back of your iPhone.
Done. It doesn't run Siri, but screw that. Enjoy!
