Hi Catherine. This is specifically a Haskell mailing list. You know that, right? Its main concern is for programmers to use the Haskell programming language on the iPhone. I only ask because your question is a rather general question. It seems that the third result in Google for "iphone mailing list" is Haskell's, which makes me further think this might be a mistake. Sorry if this isn't the case. I'm not sure where there is a mailing list for the iPhone. I looked on https://lists.apple.com/mailman/listinfo but it seems not to have an iphone mailing list. Alternatively there are apple's own community forums for the iphone: https://discussions.apple.com/community/iphone Apologies if you are a Haskell programmer, just trying to be helpful.
