Thebikiniforum.com now supports the iphone!
You can use TouchBB to read and post to the forum. All BBCode is supported when reading, but posting pictures is not quite as easy...
The gallery is only available through a browser...
It's pretty cool to read the forums on the go and for quick replies..
Enjoy!
