Should Governments ban the iPhone?

With the burst of Apple's security bubble most governments should now be concerned about the iPhone usage by the government officials and employees.
 
Apple's 'security' armor comes from the free software technologies it uses as the base, notably BSD. With the emergence of devices like iPhone and iPad, where Apple is using more of its native code, this security armor is vaporising.
 
Apple devices have recently seen some of the most serious attacks – hijacking of iTunes accounts, App Store compromise, iPad user email IDs exposed, a PDF hole giving criminals access over your devices, to name a few. The era of 'secure' Apple devices is over.

In addition to the BSD provided security, Apple's 'mythical' security comes from the restrictions it puts around its devices which is like telling 'you are safe in your car as long as it is parked in your garage'. That I don't think is a practical security.

Android on the other hand is secure by design as it is based on the most advanced kernel's in the world -- the Linux kernel. This is the reason most mission critical businesses now use Linux.

Unlike Android which is open source, the closed source nature of Apple technologies like iTunes makes it impossible for end users to know what is happening to their information and data.
 
According to The Register, "The German government has advised ministers not to use BlackBerry and iPhone devices due to “a dramatic increase of attacks against” its networks."
 
According to a report in Handelsblatt a general ban on the use of smartphones in certain German ministries is also being considered.
 
Federal Interior Minister Thomas de Maizière told Handelsblatt that ministers and senior civil servants had been told to instead use Simko2 gadgets offered by T-Systems, following advice from the German federal office for information security (BSI).
 
Shouldn't government employees and officials use open source based technologies like Android so as to have complete control over their communication and data?

Comments are invited, but be nice -- make no mistakes you bought an Apple device, Apple did not buy you!
