Wanting to buy an unlocked iPhone 4 or 4S for my girlfriend for Christmas. She has TMobile, which we have been having problems with. Her phone hasn't worked right since day one. They have replaced it numerous times with refurbished models that are worse than the previous one. Since she added her mom to her plan back in January, she cannot upgrade her phone until January 2014. I'm looking for any advice or resources for buying an unlocked iPhone. Wasn't sure if eBay would be reliable enough for something like this.
