Just to put any fears to rest, we are still working on CrossTalk but it has been delayed due to BioLock development, we have only so many resources and something has come up with BioLock that has put it ahead of everything else. CrossTalk was due to be released into beta now on the BB and Android platforms but it looks like it will be pushed back a little. I don't have a specific time, but I assure you all is well and progressing nicely.
I can say that Video calling support has been dropped for the time being until a later date. Frankly it creates more headaches than its worth at the moment.
