I too am on ATT and T-Mobile (my previous provider) sucks in signal strength by my area.

And if I have to tether my N900 to my N95 to connect to ATT, then whats the point of a convergent device ? But good to know thats a worst case scenario.

If T-Mobile's 3G coverage has improved since then I may switch (since its true NYC where I work - has bad ATT reception due to iPhone usres overload) to T-Mob.

But I still think Nokia will bring multiple devices for the different spectrums, but only after letting T-Mobile ride their 'exclusive' arrangement deal for some time.
