Yummy has only been available on the App Store for a couple of days now so I’ve not got a lot of feedback about it yet. However I have seen comments posted about other applications and so thought I would pre-empt your questions with this post. Feel free to ask further questions in the comments and I will do my best to answer them.
What happens if I add a new bookmark when I’m offline?
It goes without saying that accessing your bookmarks without being online is going to be somewhat limiting. Having said that, Yummy goes to some lengths to make sure that none of your edits go missing. If you lose connectivity, it will queue up all your changes and send them to Delicious.com when you’re next online.
Can I get an evaluation copy?
Unfortunately Apple does not allow this possibility in their App Store. There is no other way to distribute iPhone applications on a large scale.
