I have an iPhone 4 on tmobile $50 a month… 3 days ago my Internet was at normal 3G speeds and all of the sudden one evening the speeds dropped horribly and they have stayed like that.It's NOT because I was on the 500mb they offer of 4g I was already on the regular speeds. I called tmobile and they said its it says the computer shows my service is working without restrictions or anyhing. They said its my phone but it isn't because I already tried other tmobile SIM cards in it and it works fine! Any help? Anything I could do? My data speed is horrible!!! Possibly worse than metro pcs
