There’s the grab for you, folks. T-Mobile’s posted a software upgrade for RIM’s latest release, the device that’s made us so long-winded – the BlackBerry Pearl. This is software upgrade 188.8.131.52, and really, there’s nothing to report about it. Just giving you the heads up – it’s here. (Well, according to various sources, it’s all just text right now – the actual upgrade should go up no later than tomorrow, November 18).
