Don't worry, all the fuss about BlackBerry being blocked is just that - fuss. All the countries making this political charade just want a piece of the pie - a server installed on their territory so that they can continue to eavesdrop on their citizens, as is apparently the norm in those countries.
There will be no bans of BlackBerries, and that's pretty much guaranteed. The governments in those countries know that the moment they ban BlackBerris, the business community will serve them a massive dose of backlash, last but not least from all the telcos making HUGE money from selling BlackBerry devices and plans.
So don't worry, grab a beer, sit back and enjoy the show.
