And with the Official iPhone SDK just around the corner..
The Official SDK appears to be a bust... for the moment... It is targeted to the iPhone/Touch firmware v2.0... and that isn't "scheduled" for release until laste June/Early July... And it appears that the applications written with the SDK must be distributed through official Apple channels... Which will make distribution of any frontend problematic at best...
That could be done via the use of a web-server, using java...
That wouldn't work... The iPod Touch/iPhone does NOT support Java!!! (The one thing I hate about the iPhone!)
