We're starting to roll out MVS 5.1 (BlackBerry Mobile Voice System) at work but unfortunately my Bold 9900 with OS 7.1.0.267 is not supported by the MVS client. I'm told I need to be at OS 7.0.x and use MVS 5.1 Maintenance Release 1 to be able to do wi-fi calling. Is anyone aware of a later beta release that supports 7.1.x devices?
