The guys over at BBLeaks are on top of these beta OS leaks.  This time we have OS 5.0.0.530 for the BlackBerry Tour 9630.  We are still waiting on an official 5.0 release from Verizon, the experts say that is when the 9650 will be released.  In the mean time I will just enjoy the new beta leaks.  To install this on your Tour make sure you delete the vendor.xml file and remember this is NOT official, install at your own risk.
