Every so often i have that problem too, maybe has something to do with the upgrades. Apparently this algore darpanet cloud thingy can tell if you are on your phone and sends you to the 'm.' simplified realm when you try to see.
A trick i've found often works is to edit the url, lose the m. and add a statement along the lines of '&redirect?=false' in there somewhere.
On tsptalk when i get the mobile dummy screen i click the little plus sigh to login but don't. Click the button on the bottom that says 'view full site' or something. It will take you to the traditional screen where you last 12 posts and recent blogs and such. Access site from that bookmark through browser not from the icon shortcut on one of your desktops. Setting should hold until it changes, ?maybe next upgrade? Viewing site just fine right now on samsung galaxy.
Don't ask how i figured that out. All i did was click some buttons, on a bottom. It was hard to resist.
