Wanted to re-use this thread - but in regards to the N900 ...

Since the N900 is tied to T-Mobile, can we not use the Mifi (on Sprint or Verizon) to use as a 3G modem - and keep the N900 always on connected to Wifi over the Mifi (for those not wanting to switch to T-Mobile for fear of bad voice data coverage for some areas) ?

Will always on over Wifi be more of a battery drain on the N900 than always on over 3G ?

Also there is the donwside of carrying another extra device and also the Mifi doesn't last a full day on battery either .

So will the N900 be usable with the Mifi ?

Worst is the outrageous data plans with the Mifi.
