What do you want an iPhone library to do for you?
<p>I'm an undergraduate university student who also writes iPhone applications.  Next year I'm expected to do a final project, something that lasts the full year and involves a fair bit of software engineering.</p>

<p>My original plan was to write an object-relational wrapper around SQLite for the iPhone (or rather, to massively clean up and extend one I already have) and ultimately release it as open source.  Unfortunately, with Core Data being added to iPhone OS 3.0, that's no longer really necessary.  (At least, that's how it seems to me; any opinions on this?)</p>

<p>However, I'd still like to do a useful, technically interesting iPhone-related project next year.  So here's my question: what do developers need?  What sort of problems do you encounter in your apps which seem like they could be handled by some sort of library or framework?  My focus is generally more on utility, productivity, and communication apps than games.  And since I'm proposing this to a university, something that's either theoretically interesting or attractive to potential students would be preferred.  And of course, it'll need to be something that they <em>haven't</em> added to the new version of iPhone OS.</p>
