Benson, I appreciate your attempt to help.

I probably have heard of NAT before, but no, I didn't remember it consciously if I have. So thank you for that. My newbishness is less severe now.

Moving on: whatsmyuseragents.com reports essentially the same thing yours does. Mozilla/5.0 etc. etc. Maemo Browser etc (I'll copy and paste if you feel there's relevant info there).

I just go directly to "www.gmail.com", which then loads the same page "mail.google.com" does (I've tried both now that you mentioned it), and then from there I log in as normal, only to be taken to the mobile page.

But getting back to the 'evidence' part... Honestly, I have yet to download something like Wireshark to monitor the internet traffic on my N900 in detail, but here's what GMail's own "last account activity" window says (This is the window you get when you scroll to the bottom of the page in basic HTML and normal views and click the details link next to "Last account activity: __ minutes ago."):

Browser * United States (FL) (24.92.29.209) 10:54 pm (0 minutes ago)
Browser * United States (FL) (24.92.29.209) 10:14 pm (39 minutes ago)
Browser United States (FL) (24.227.52.106) 8:59 pm (1.5 hours ago)
Mobile United States (FL) (24.227.52.106) 8:59 pm (1.5 hours ago)
Browser United States (FL) (24.227.52.106) 8:19 pm (2.5 hours ago)
Mobile United States (FL) (24.227.52.106) 8:19 pm (2.5 hours ago)
Mobile United States (FL) (24.227.52.106) 7:42 pm (3 hours ago)
Browser United States (FL) (24.227.52.106) 7:34 pm (3 hours ago)
Browser United States (FL) (24.92.29.209) 8:51 am (14 hours ago)
Mobile United States (FL) (24.92.29.209) 8:48 am (14 hours ago)

The asterisk is the activity from the current session - and that's from my home computer.

The six under that are the ones done from another household, and the last two are done from the N900 from the same place as the 'current session' (given your explanation the IP address thing makes sense now). Anyway, You'll notice that, at least for the two more recent pairs, the activity was registered within the same minute.

This is where GMail's table stopped, but earlier this morning when I was first noticing this problem, I noticed that if I logged out then logged in, it would list both in the same time slot too. My guess is that the not-identical time stamps for the bottom two pairs that I do have are from longer sessions while I was trying to get GMail to log out the 'mobile' connection, and then toggle the view from standard to HTML and back to see if it switched. The problem was is that the 'mobile' connection was logged back in as soon as it was possible to even check (my guess is GMail didn't record every single log-in/log-out of the Mobile connection, but noted them occasionally, or something. *Shrug*).

As for why I think my connection is the 'browser' one and the 'mobile' is some background device one? When GMail has an account logged into from two or more connections, and you scroll down to the bottom to the part where it tells you about this, and click the details, gives you the concurrent session information in a separate table. And in this table (and I just tested again just to be sure - Mobile connected at 11:15, browser at 11:16. I'm sure the difference was seconds at most, and I don't know if it means anything that Mobile was first this time), it says "Mobile" for the concurrent connection, not "Browser". Since the history shows only two connections being established, the Browser and the Mobile ones, the fact that the other session is the "Mobile" one suggests the Browser is the one you, as the user, are viewing everything through. That, or GMail royally glitches on me every single time I've logged into it from my N900 since this started.

In other news, I briefly tried going to the URL GMail normally takes you to when you are logged in "mail.google.com/mail/?shva=1#", since I wasn't sure if that would help - no luck. It just rerouted to the mobile version.

- Edit -

Creamy Goodness, I do hope you read the entire thread since something close to this was suggested and I and someone else already reported something similar did nothing.

There's no button for 'classic' view in either the basic HTML or the mobile versions of GMail that I could find. There was a 'standard' view, but it just assumed that the 'standard' for your device was the mobile view.
