SMF4iPhone is a "theme" meant to mimic an application using the browser. It's nice, but not what I had imagined.
The PHPBB app that I found can be found at ...
www dot messageforums dot net slash iphoneforumreader.php
The app that I had in mind would potentially allow for offline viewing (storing messages on the device). An iPhone is always connected, but I've got an iPod Touch that is not always connected (only if wifi is available).
Since what I had in mind isn't browser based, most (if not all) of the customized themes would be rendered useless. This app would be designed for on-the-go reading and posting and easy navigation using some of the UI design stuff that Apple provides in it's sdk.
My wife is going to install SMF4iPhone on one of her forums to check it out.
Also, I think it would be nice to have one app that works with ALL SMF forums right out of the box. If I use one forum that has SMF4iPhone and go to another that does not use this theme, I'm going to be severely disappointed. And would that admin install it just because I asked?
If a theme for mobile devices was standard, I don't think this would be needed. This forum looks nice on a computer, but does not have a nice UI for my iPod. I have to scroll and zoom to do anything. Standard hyperlinks have to be zoomed quite a bit to be accessible via a touch screen.
Thanks for the input. Keep it coming!
