However I had to demo something that my phone, a Nokia E61 can do that neither of those can.
I turned my phone off, pulled the SIM card out and rebooted.
Then I dialed our office phone number hit call, told it yes you can use wifi while in off-line mode, and then moments later our phone rang.
(Actually I was surprised too, apparently my SIP phone/Gizmo account still had some demo minutes in it.)
Then later I found there's a technology preview of Qt for the Nokia S60 phones. (which mine is one of).
