How do I upgrade from the original iPhone to the iPhone 4 on T-Mobile?

When the first iPhone came out, I bought it as soon as I could and jailbroke it so I could use it on T-Mobile. Now I want to upgrade to the newest iPhone and use it with my existing plan which works great (I pay t-mobile some standard data rate, I don't have 3G, that's okay, and everyone is happy). What are my options? Is this even possible? Any and all resources welcome. Thank you!
