Retro Rotary GSM Phone
I’m a HUGE fan of retro tech, HUGE FAN. Matter of fact in my travels I love visiting the Computer History Museum so the PRP v1.1 Retro Rotary Mobile Phone has a very warm spot in my heart. All you need to do is insert a SIM card, and you have simply the most awesome mobile (?!) phone. It even rings with an incoming call. Only problem is the price-tag: $499.00.
The GM862 cellular module from Telit works within any country that has one of the 900MHz/1800MHz/1900MHz cellular bands (90% of the world). Each phone is specially built to customer needs. Please allow a 2-3 weeks for delivery. The battery can run the phone for 4-5 days and is charged by unscrewing two screws on the bottom of the phone, opening it, and attaching the charger.


I while ago hack-a-day showed how you can make your own for a bit cheaper here…

There’s another post somewhere on hack-a-day of a guy that did it where you can charge it by plugging the phone cord into a regular phone jack.
