Nokia released an application (mnotify) to monitor your Gmail inbox from an N800. Here‘s an installation howto.
Mnotify has a menu command to open your Gmail inbox in the browser (View inbox). It uses HTTP, not HTTPS. So I wondered if the mnotify also used HTTP for mail checking?
It doesn’t. I looked at the traffic with tcpdump, and the mail check is done with HTTPS. So if you’re on a wireless network you don’t trust, it’s safe to let mnotify check your mail, but don’t view your inbox with it. Use HTTPS to view your Gmail inbox.
I’ll use my N800 to connect to an untrusted network next week ;-)
