I came across two posts over the weekend that really perked my interest and decided to share them. First are some live screenshots of OS 4.5 and BES 4.1.5 SP5 live in action. This is some pretty hot stuff delivered courtesy of Jibi from BoyGenius showing us just what to expect in these new releases. It seems like we will be waiting at least until WES for a release but it is promising. My favorite features are the HTML email and the remote search for email. Check out the screenshots on BoyGenius at this link.
The second article is not really new but is a nice consolidation article by Sascha Segan of PC Magazine about what features in OS 4.5 you can expect to see on your device. I would highly recommend checking out what he has detailed. It is great to see that PC Magazine is putting its weight down on RIM for some answers on OS 4.5.
