Move an iPhone 4 from AT&T to Tmobile?

I currently am on my parents plan with an iPhone 4 via AT&T for my phone/data. I would like to keep my phone and number, but move to T-Mobile on to my wife's plan. Is it true that 3G will not work as this article suggests? Can I use any other carrier beside AT&T without gimping my phone? Is there any chance in the future of compatibility with Tmobile? Also: would this nullify my unlimited data with AT&T? Is it possible to get off my parent's plan and on to my own without losing unlimited data? (I was told they no longer offer it..)
