According to the lord of everything wireless, Boy Genius, starting June 28th, RIM plans to perform maintenance on their BIS servers. Not very routine this time, but to upgrade to the new BIS v2.5.

BlackBerry users have been long anticipating HTML Email support for their smart phones that it seemed like it would never arrive. This upgrade could mean long awaited HTML email support for BlackBerry devices. RIM is planning on upgrading their U.S. BIS system later this month, which will include a lunch-menu full of updates awaiting their new line of 9000 series BlackBerries.

Aside from the over-exhausted HTML support I’ve been rambling about, the update should include enhancements for OTA (Over-the-Air) upgrades, calendar improvements and some other stuff.

Your device, of course, will have to support all these great new features, but since we’ll all be using the Bold by this time next month, we don’t have much to worry about.
