I recently purchased the iSub "Lite" app for my iphone, and for what it's worth, it works great, despite not having playlists or caching available (which are available in the full version, which I plan on purchasing soon).
The problem I have with it is that I intermittantly get an error when accessing the app store, where a pop-up will come up, saying it was unable to purchase the iSub application. I can just hit the OK button and it goes away, but why is this coming up? And better yet, how do I stop it from coming up?
