I have read alot of info out there with trying to get the data plan working and alot of it is mix-matched and out of date.

I have a 3g 2.0.1 iphone running on tmobile with a universal sim card. So far no problems with using any features. Before getting the iphone, I had the 5.99 data plan and since using the iphone I have tried to figure it out and am having no luck.

I downloaded tzone hack from cydia. But I dont know what I need to do since downloading it. I looked for it on my iphone and cannot find any kind of icon or etc.

Can someone please help me out and let me know what I'm doing wrong or need to do...and please explain in easy terms as I'm still learning how to do all this modding.

Thanks s much
