Yesterday, Boy Genius dropped some whispers hinting that the long awaited OS 5.0 update for the BlackBerry Tour 9630 was coming in the next 2-3 weeks and that it was also bringing a new Push To Talk feature. As it turns out, the files needed for that new data plan using push to talk features has been turning up in the past two OS leaks for Tour owners. And from info gathered in the forums, Verizon is seemingly not really trying hard to hide it from end users either.
As posted in the forums, some skilfull folks have found through the Verizon wap website you can actually find and attempt to add the services to your Verizon account. While at this point, the files and the addition to your account doesn't mean you can get it to work. It certainly puts weight behind the timelines given for push to talk and the rumored 9650 release.
