Wow, ok. So after being leaked, released, then pulled, BlackBerry Tour 9630 OS 4.7.1.53 is once again official but this time around it's coming from Reliance and not Verizon. Of course, it can still be loaded onto your Verizon Tour if you missed out on the leak, release and pulling debacle just follow the tutorials at the bottom to get started on it. As for the Verizon official release, the forums are full of reasoning as to why - there's been no official announcement so you might want to read up on the unofficial reasons.
