I haven’t monkeyed around with the other phones all that often, but I fully expect that a lot of them are probably equally goofed. Russell Beattie keeps a mobile blog where he talks about stuff like that. It’s a good read if your into that sort of thing, or just curious.

For what it’s worth, I use all the “old school” mobile apps that have worked fine with pretty much every web enabled phone I’ve got. Those are the ones at http://wap.oa.yahoo.com.
