This morning I got a mail :
2.12 Apps that are not very useful or do not provide any lasting entertainment value may be rejected
They are really holding down new apps that they think that are not usefull. With their new rules they can crack down any program, although you did a fine job.
If all your app does is play a file, then no, its not going to get approved. It has to have actual functionality. They're not allowing anymore apps like that, along with fart apps, or things that are just plain dumb.
Spice yours up a little, have it read some RSS feeds, a contact page, SOMETHING besides just playing a file.
