That would be like asking if the President of the United States's phone were left somewhere it could be compromised by a foreign agent, don't you think? The really FUNNY thing is that while she did have an iPhone, it was her PERSONAL phone. . . which she did not use for government business. She used a government issued "secure" NOKIA phone for government business:
Angela Merkel using her government issued supposedly "secure" Nokia phone
at the Bundestadt just before the news of the NSA wiretapping came out.
Snowden reported that the NSA and CIA had been tapping the German government phones since 2002. . . and that Obama had specifically authorized tapping Merkel for three years prior to Snowden fleeing. LOL!
