Seems noting is really safe with RIM these days. Here is a leaked copy of RIM’s upcoming BlackBerry Desktop Manager 5.0, which might come in handy if you planning on installing those leaked copies of OS 5.0 for the Bold and Curve 8900. Anyways just be aware that this may not be the most stable version available yet as it is still in beta testing but it doesn’t hurt to give it a shot. Any luck at all we will see RIM release this early next month at WES with OS 5.0. Stay tuned!
