view story

http://forum.xda-developers.com – Hi, I just purchased the DNA and registered it with the mobile. I am having trouble with the tower connections. I can only seem to get on EDGE GSM and some other really slow networks. I know the DNA supports the 1900and 2100mhz bands and t mobiles hspa 4G works only on 1700mhz. So if this is true, when is t - mobiles new 4G 1900mhz network coming to Toledo Ohio? (HowTos)
