If you're on LinkedIn, and you use a smart phone...

Well, this concerned me at first, but then I read the description of how 
it's done 
(http://engineering.linkedin.com/mobile/linkedin-intro-doing-impossible-ios):

     We understand that operating an email proxy server carries great 
responsibility.
     We respect the fact that your email may contain very personal or 
sensitive
     information, and we will do everything we can to make sure that it 
is safe.

I find this completely reassuring.  I'd expand on that, but I have to go 
buy a used car now.
