Earlier today when discussing the problem of RIM/Blackberry vs the UAE, I mentioned that RIM should not ignore this problem because "... the risk here is that other countries could (and I believe will) follow the UAE's lead on this and threaten similar shut-downs."
When I wrote that, I figured that other countries would follow suit in a matter of months. Now it seems that it took less than 2 hours for news to leak that Saudi Arabia is planning a similar move, and for similar reasons.
Reports are sketchy, but here's an interesting source. The Saudi threat put an additional 700,000 subscribers (and 700,000 subscribers' revenue) at risk.
The stakes are now that much higher for RIM.
