I'm installing OS 4.5 as I type this. It enables video recording and from what I have heard the quality is great. Some Features • BlackBerry Maps with Points of Interest (H) • Improved media player with playlist support and automatic playlist generation (H) • Voice note recording (H) • Video recording on Curve models (H) • Streaming support for YouTube and Sling Player (H) • Microsoft Office document editing with DocumentsToGo (H) • Native format attachment downloading (S) • HTML e-mails (S) • Over-the-air device upgrades (S) • Free/busy calendar lookup (S) • Searching the server for old e-mail messages (S) My favorite is the video and the you tube streaming is a close second. I can't wait to put it to the test. This is only the beta release. Only a limited amount of people were given the opportunity to download it. However, others have been trying to spread it and there are many links around the web, one of which I found and downloaded. The installation process is just about finished and I'm estimating the completion at 40-50 minutes.
