I hope I posted this in the correct section. I am planning on buying an unlocked Samsung Galaxy Y S5360 from eBay. I would like to use it with T-Mobile USA. I have done a bit of reading and got really confused about the 3G Mhz settings. I was at several T-Mobile stores and asked several online sellers if this phone will work on T-Mobile"s 3G network in real 3G mode and got completely different answers every time. To make this even more confusing, some of the eBay listings have 3G 900/2100 MHZ, while others have 3G Network HSDPA 850 / 1900 in their description. Does anyone here have this phone successfully running on the American T-Mobile network with 3G? Any help is appreciated. Thanks!
