The 4G network being up means that as a t-mobile customer, you can roam on AT&T's towers, but only once the new network is up and running (which helps t-mobile out A LOT). T-Mobile has contracts with Comcast all over the country to install signal boosters and necessary wiring throughout major cities, for the t-mobile 4g debut. So I'm not joking, if you're in a major city and you see a Comcast truck working on electrical stuff, it's probably for t-mobile.

T-Mobile's HSPA+ is not 4G. Although it will have theoretical 21 MB speed it is still based on a 3G technology and is not officially 4G. That said, T-Mobile's 3G phones do not have the 850/1900 3G bands only the 1700/2100 band that they actually use for 3G, meaning they could never roam on ATT's 3G (HSPA) or 4G (LTE) networks. T-Mobile phones can roam on ATT to make calls and use the 2G EDGE network as all T-Mobile phone have at least the 850/1900 GSM bands. The latest 3G phones, MyTouch and later, have a 7.2 MB top speed so with the HSPA+ upgrade they will blazing at near top speed. The only HSPA+ device (Rocket web stick) in use right now is seeing about 6 MB actual usage speed.
