T-Mobile (fuckwits that they are for not sorting me out a Milestone), are gearing up for 4G.
They're preparing to launch a 4G tablet, and yes, its Android.
Even if the blog you quoted was correct, it would be irrelevant anyway as T-Mobile UK doesn't have a 4G network, won't have one in 2010, and possibly not even 2011.
The Vega tablet is not 4G.
