Until now, T-Mobile's HotSpot @Home
WiFi calling service had strictly been a consumer venture -- but now, it's time to rope the suits in on the fun. Many of the handsets currently in T-Mobile's HotSpot @Home stable aren't exactly prime workplace material, but a few -- T-Mobile's WiFi-enabled BlackBerrys, to be specific -- fit in rather nicely, and it seems that the BlackBerry line is exactly what the carrier will be using to position the service. There'll be a flat rate that applies to get unlimited calling over WiFi (just like consumers pay) , and considering that businessfolk are probably the last remaining niche of ultra-heavy voice users, this could be a power play for T-Mobile that wins over a few of those lucrative corporate accounts.
