What iPhone SDK applications do you want?

We don't often conduct user surveys here on iPhone Atlas, but with Apple still apparently planning to "have an SDK in developers' hands in February," and February rapidly coming to a close, we'll bluntly ask: what third-party applications would you most like to see materialize after the advent of the software development kit?

A number of developers of unofficial third-party applications have told us that they're planning to leap into the Apple-sanctioned realm post-SDK, but there are undoubtedly those who are waiting to see a distribution framework and other specifics before investing in the platform.

So, what's your iPhone application concept? Let us know at info@iphoneatlas.com.
