I installed this Vodafone OS 6.0 on my T-Mobile 9700 on the T-Mobile network and it disabled all mobile network connections unless there was wi-fi. Network diagnostics implied it was because of the UMA connection.
It also wiped everything on the device (which I wasn't expecting but probably should have). After I restored my back-up file on OS 6.0 the mobile network still didn't work unless there was a wi-fi connection. I called T-Mobile who were quick to tell me they didn't have an operational 9700 version of OS 6.0 still (as noted in the above comments) but that they -did- have the 9780 available (512MB of memory instead of the 9700 256MB) with it today and that they had no APN settings or service book help to further the network connection without the help of a wi-fi connection. Strange how everything worked in wi-fi but the mobile network wouldn't connect otherwise, seems fishy to me.......
WIthout mobile network capability I quickly erased the the OS 6.0 from my system (otherwise the Desktop Manager will automatically use the 6.0 version), downloaded and installed the 5.0 version from blackberry, and then again restored my back-up. Everything is back working again but it has been a pain to get my Enterprise system and all my files back in synchronization again (as many people know) and all in the middle of a work day (took about 2 hours).
Needless to say, here's to hoping a version really does come out from T-Mobile at some point.
