Despite Cingular's claim of being "the network with the least dropped calls," PC Mag's Sascha Segan finds that T-Mobile's version of the BlackBerry 8700 smartphone, the 8700g, actually outperforms its 8700c cousin in terms of call quality. Other improvements upon the Cingular model are T-Mobile's addition of two key software features: the OZ semi-universal IM client (no Gtalk, and AIM users are restricted to their small mobile buddy group) as well as the first implementation of the Yahoo!/RIM partnership we heard about last month, in the form of a handy Y! Mail icon pre-loaded in the launcher. Besides these small differences, however, Sascha finds the 8700g to perform almost exactly the same as the 8700c -- that is, very well. Email and texting are a pleasure, attachment support is good for all but PDF files, and the crisp screen delivers web pages cleanly (albeit at EDGE speeds), making this seem like the new go-to device for the Mob's business clientele.
