An incoming BlackBerry Internet Service 3.0 upgrade will apparently be offering Windows Media Audio support and the ability to work with OpenOffice presentations, spreadsheets, and documents. All of that is, of course, on top of the previously-leaked features of two-way GMail sync and GMail labels. Sometime after it rolls out this March will be a 3.1 upgrade that will include Google Calendar syncing, and contact syncing for Hotmail and Yahoo (which the latest BIS already does for Google). BIS is largely used by consumers (rather than those issues BlackBerrys through an employer) which is a segment that is growing rapidly. Although keeping BES software fresh and up-to-date, BIS upgrades are quickly going to become just as important as the average non-enterprise consumer becomes a bigger and bigger part of RIM’s userbase.
