Stop google from indexing TP wap2

[estecb]

Hi, for some reason google started to index my wap URLs lately (it wasn't some days ago), I just did a quick search ( http://www.google.com/#hl=en&safe=off&q=tinyportal+wap2 ) and I found that it's doing the same with this site.

I wan't to know if there is some way to stop google from indexing the wap URLs and start indexing the regular URLs instead.

I'm running TP 0.9.8, but it looks like the issue is on TP 1.0 as well.

I just realized it can be all fixed by adding canonical tags...
I found some info about blocking the URL's from Robot.txt but I'm not sure about the side effects.
