I been looking at iphone 4 and 4s on ebay and deciding which one to buy. I saw one that is pretty expensive for a new iphone 4s 32gb... its 480 dollars new. Yes i know that is a lot and its better buy an iphone 5 instead but i dont like how the iphone 5 looks... it looks too big. The person advertised this as unlocked... however they said it doesn't work with tmobiles 3g/4g plan and only work with t mobiles 2g plan. Can someone explain this? Im confused because i thought an unlocked iphone worked with all carriers. This is the iphone im talking about http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=281166627645&ssPageName=ADME:X:RTQ:US:1123 Can someone explain why it doesnt work with tmobile 3g/4g? I emailed him and asked him and he said it only works for tmobile 2g and obviously i know 2g is very slow compared to 3g.
