David Cameron, the UK's Prime Minister, managed to give BlackBerry some free marketing this week, although I'm pretty sure he didn't do it on purpose.
Whilst conducting a Q&A session in Dubai his BlackBerry decided to 'ping' and he quite openly reached into his pocket and told the audience that it was his BlackBerry.
It made me laugh as a while ago BlackBerry UK tweeted David Cameron reminding him to hold down the 'Q' key on his keyboard to switch between profiles. I suspect David may have learnt his lesson!
