I have an iPod Touch and want to buy an iPhone. But my friend recommend me to buy a device named "Apple Peel 520" ( http://www.tinydeal.com/yosion-apple-peel-520-ipod-touch-to-iphone-convertor-px8838--p-13367.html ）which can convert the iPod Touch to an iPhone. Then I have no need to spend more money to buy a new iPhone. It sounds amazing, but I doubt that if it is worth. What do you think about it? Did anyone ever hear about or use that?
