The big thing about the 3310 was that it did not have an obvious aerial. does not seem to be a big thing now, but at the time it was revolutionary, since it meant the phone did not snag in packets and snap the thing off. Ericssons best at the time still had asmall but significant shark fin aerial.
The other big "innovation" was snap on covers which provided some customization. Again does not seem much now, but up to that point phones tended to be corporate black.
