Seeing as the new iPhone5 is still a ways out, and may be getting further out in time, is it time to change your email signature which says "sent from my iPhone" to something more, well... relevant?
How about this one?
"sent from my cruddy old iPhone since I can't get the iPhone5 for weeks yet"
or
"sent from my trusty old steed, my iPhone4, which is sadly nearing the end of a long and fruitful relationship with me"
or
"Verizon or AT&T? Or Sprint? Or Verizon? Or, oh... Verizon?"
or
well, you make one up.
