Now that Barack Obama is President, the question on weather he had to give up his beloved BlackBerry should be answered soon. According to a report by Marc Ambinder from The Atlantic, via CNET Obama's BlackBerry has been outfitted with a encryption software and now he is supposed to be able to use it for personal use. Update: Obama administration confirms that Obama will continue to use his BlackBerry.
Last week it was speculated that Obama will get a large-sized Windows Mobile Phone from General Dynamics.
I also thought the much bigger problem than security for the President is actually that all written messages have to be opened to the public after his presidency.
For instance if he would email a little love poem on his BlackBerry to his wife, that would have to be published in a couple of years. That is why its best for a President to avoid writing as much as possible.
