I'm setting up a blog using wordpress, (check it out at http://fmsantas.com ), but I think I would like to use mobileme as my webhosting. Can I use it with wordpress or can do I NEED to use iweb? If so, can I edit/post on an iweb blog on mobileme via my iphone?
You don't have to use iWeb for MobileMe to host. I don't know how wordpress works, so I don't know if you can update with your iphone or not. This is the support article showing how to upload your non-iweb websites to mobileme for hosting.
