Made a mistake and installed 3G on Iphone4

[Madria]

Hello,
I just got an uograde to an Iphone 4, I made a mistake and changed my network to my old phone's 3G. Now when I reset my Iphone 4, it says 3G. Is there anything I can do myself to restore to an Iphone 4 besides take it back where I bought it at? I did restore, reset, you name it....nothing but 3G.
So disappointed. Please help.

See answer in iPhone 4 Sub-forum. iPhone4 is not 4G, it will always only work on 3G, and will only say 3G in the top left-hand corner. Make sure you do your research before you buy something.

?? Not sure I understand but the second post would tell me your expecting a 4g network on your iPhone 4?

It does not have 4g
