If you happen to own a BlackBerry Tour 9630 and are feeling a little bit more adventurous compared to other smartphone owners, why not give the OS 22.214.171.1248 leak a go? After all, this is not an official release, so the chances of things running awry is much higher than that of Iraq carrying WMDs all those years back. Installation of this OS leak is done at your own peril, so make sure you always make a backup! Apparently, this update will come with a Push-To-Talk feature that costs $5 per month over Verizon’s data network. Word has it the official version will be released within the next month, so stay tuned.
