A very thorough analysis, thanks. In that light, how do we explain the
following:
my phone is 'off' the network (the i is not blinking)
someone sends me an email and immediately my phone connects (i starts
blinking) and the mail is delivered.
Exactly how is the handset getting notified of the incoming mail if it's
not yet on the network?
I am confused.
