Albeit a tad bit late, the T-mobile BlackBerry Pearl 8120 is finally seeing the OS 4.5 Update that was promised so long ago.  Starting tomorrow, March 13, T-mobile Pearl owners will be able to get their hands on RIM’s OS and finally have a glimpse into what HTML email means on their handheld.  Along with the HTML email for BIS accounts, music / video streaming, free / busy calendar look up, remote search for emails on server, attachment download / document editing, wireless software updates, myFaves 1.5, an updated UI, Wap 2.0, Voice IT policy controls, BlackBerry Maps enhancements, and GSM / EDGE toggle capabilities will be included.

Pearl 8120 owners will be able to download the OS 4.5 update from http://www.t-mobile.com/bbupgrade sometime in the morning.  As usual a high-speed Internet is recommended for the download and you will need to backup your existing device information prior to updating the OS.
