With any luck, we should have honest-to-goodness UHub iPhone and BlackBerry apps up and running in about a month (I just spent a good part of a perfectly beautiful Saturday designing splash screens and icons).
The apps will have the UHub breaking-news goodness you'd expect, but also stuff like restaurant and store listings and reviews, all searchable and mappable. To get a rough idea of how that'll work, go to www.locallite.com/search.php and search for something (say, "pizza" in "Boston, MA").
It's obviously way more sophisticated than anything I could pull off on my own; I'm working with a local startup called Zebek that's built what seems to be a cool back end for mobile information-based apps. Blatant commercial pitch: If you own a business in the Boston area and want to reach the sort of wicked awesome people who would use a UHub app, contact me.
Droid users will notice I did not mention you. Unfortunately, there's no Droid app just yet. In the short run, there will be a Web interface for you (and users of other mobile phones and devices). But a specific Droid app is in the works.
