HTC has gone ahead and quietly released a Windows Mobile 6 upgrade for their S620 smartphone. The S620, for those that don’t remember, is the generic version of the T-Mobile Dash. Seeing as T-Mobile and HTC dropped an official Windows Mobile 6 upgrade a while back, we’re a bit shocked it took this long to take care of the unbranded version. That said, beggars can’t really complain all that much, right? The update handles the usual host improvements, and doesn’t provide much in the way of innovative new features, but it certainly gives a bit of new life to a handset that’s getting a bit long in the tooth.
