Not redirecting: Opera mobile 10.1 on a nokia n95-3.
Opera/9.80 (Android 2.1-update1; Linux; Opera Mobi/ADR-1107051709; U; sv) Presto/2.8.149 Version/11.10
Steps to reproduce: 1. Delete all cookies and other privacy data, 2. Reboot the phone, 3.Type in www.wikipedia.com/wikipedia in the location bar. Now you end up on the normal (immobile) Wikipedia.
Step 1 is necessary because mobile/immobile site preferences may be stored in a cookie and we need to ensure that the cookie isn't there. Step 2 ensures that the browser is restarted (not sure if needed). When doing the same thing in Opera Mini on the same phone, I'm taken to the mobile version of Wikipedia. URL syntax chosen to minimise the number of keystrokes necessary (very useful on a slow typing device such as a phone): there's a shortcut for ".com", "www." is already there and no "wiki." just gives a redirect to the right place.
Maybe the problem is that Opera Mobile for Android mentions both Linux and Android? The former might suggest a desktop computer... (22.214.171.124 09:33, 4 August 2011 (UTC))
Just for comparison, the user agent string for Opera for Linux desktop computers looks similar, but doesn't mention "Android" or "Opera Mobi": Opera/9.80 (X11; Linux i686; U; ja) Presto/2.9.168 Version/11.50. I wrote the initial message too, but from a different IP address. (126.96.36.199 22:13, 4 August 2011 (UTC
I use Opera Mobile 11.1 on Android as well, but seems that it has been fixed. Hankwang 12:52, 7 August 2011 (UTC)
Seems to have been fixed for me too. (188.8.131.52 12:50, 8 August 2011 (UTC))
Mozilla/5.0 (Nintendo 3DS; U; ; en) Version/1.7455.EU -- My Nintendo 3DS isn't getting the mobile version. It was being redirected properly earlier today briefly, for some reason, but I don't think I've pressed any disable button... Anyway, I figure it would help regardless if I just dropped the 3DS's useragent here3DSes with older system firmware don't have version 1.7455. I'm not familiar with editing Wikis, sorry if I'm messing up the layout or something.
