i've been using TapaTalk to access many of the forums i follow. it's a smartphone native app that gives a very user friendly way to read threads and post to forums.
it supports vBulletin (this forum) but needs to be permissioned. details are here:

and obviously here:

maybe there is enough interest such that we could access the forums from our phones with this nice app?
thanks in advance!
