Brand new Glaxy S3 had it as a new connection on T-Mobile decided it is not for me and would like to go back to Apple... It is blue in colour and is 16GB.... works really well and would be good for someone who is cool with Andriods. Willing to do an straight exchange with an Iphone 4S 16GB or higher if anyone has one they want to swap. Any offers welcome.
