I hear rumors that it is already out! I heard someone say go to the T-Mobile site and grab it BUT its not there! Still 4.2.1.107 or whatever. If anyone knows how to get a hold of 4.3 or how to get in from BB (LEGALLY) I will be extremely happy... or if you know if its even out or not.
Desktop Manager adds support for Lotus Notes 8 and removes support for Outlook 2000. Newer versions of Outlook are still supported. It is a bit of a facelift, as well.
I recommend sticking with Desktop Manager 4.2 SP2 as there are some issues with 4.3.
Jack, you're referring to the Handheld OS 4.3 version. I've seen a newer beta of the 4.3.1 OS and the camera was fixed. OS 4.3 will come soon. When it does it will be big news and you won't be able to miss it.
You'll need to search around the forums as there's lots of threads about what's in 4.3. One of the site admins here did a full thread on it with videos and everything.
