Many Android phones and tablets are beginning to receive the newest version of the operating system, called "Ice Cream Sandwich" (version 4.0). A change in the way this newest version authenticates webpages in certain browsers is conflicting with our login pages, which is why you'll see all other pages load correctly on your device, but still can't log in. Specifically, we know of conflicts with the default Android browser, as well as the mobile versions of Chrome and Dolphin. Some have reported errors with Opera, though this seems to vary by the specific device.
Our developers suggest using the mobile version of Firefox as an alternate browser on your Android device until the authentication issue is resolved, as Firefox bypasses the problem entirely and the login page loads correctly. Firefox can be downloaded for free from the Google Play Marketplace.
**Please note that this problem has only been affecting phones upgraded to Ice Cream Sandwich. Android phones still running version 2.3, "Gingerbread," should be able to load the login page regardless of browser used. (Tablets running version 3.0, "Honeycomb," should follow the same instructions as for ICS.)
