If so, how well does it work? I currently have the T-Mobile Sidekick LX 2009 which is under the 3G network. I want to buy the iPhone 3G, but I need to make sure that it won’t run slow, and most importantly, that my plans (my faves, unlimited text messaging, unlimited internet browsing) will still work correctly. Help? Thanks!

It will only be able to run on T-mobiles EDGE network, not 3G. This is because t-mobile and at&t use slightly different technologies for their 3G networks.
The HTC Hero is a new android phone that will be coming out for t-mobile soon and has 3G. It is similar in size and shape to the iphone, and runs android which is a fantastic platform.

As long as it is unlocked, you can use it. Otherwise, it will not work on T-mobile.
