Speaking to attendees at the White House for an event promoting health care laws and legislation, Obama explained why he relies on his BlackBerry, saying:
"I'm not allowed for security reasons to have an iPhone."
BlackBerry is well-known for its security credentials, due to additional levels of encryption not usually provided over secure Internet connections. Research in Motion ensures that messages from a BlackBerry are already scrambled before reaching secure connections, where they are then unscrambled once they reach their overall destination. The keys used to scramble and unscramble data are held by the company or group that subscribes to enterprise systems.
Due to these high levels of security, BlackBerry mobile devices -- despite bombing marketshare in the consumer realm -- are popular within the banking industry, politics and corporations.
Obama's phone is a modified version of the standard BlackBerry device, but he struggled to hang on to his mobile after claims surfaced that German Chancellor Angela Merkel was being monitored unlawfully by U.S. spies.
