OS 4.6.0.297 for the BlackBerry Bold on AT&T is once again available after an initial release followed quickly by some technical difficulties and a retraction of the firmware earlier this month. The big deal with this particular patch is the addition of a free visual voicemail application, allowing subscribers to cruise through their voicemail without having to dial in. To get started on your Bold, go to RIM’s software download site for AT&T, and pick out the BlackBerry 9000 from the drop-down menu.
