There are still tons of rumors around the web about the iPhone Nano, a mini version of Apple’s iPhone, if you cant wait until Apple release a mini version of the iPhone, you could always get one of these Chinese knock-off of the iPhone, the CECT M188.
As you can see from the photo the CECT M188 even comes with an Apple boot screen, it measures 86mm by 4mm by 1mm, which is about the same size as a credit card.
It comes with a 2.6 inch touchscreen and stylus, it is triband GSM which works on 900/1800/1900 networks, and has support for dual sim cards.
It also features GPRS data connectivity, an MP3 player, a video player and an FM radio, here’s a video of it in action.
The CECT M188 is available for about $100 from Bigboxstore, personally I would wait until June to see if Apple release an iPhone Nano.
