Pretty big round for uLocate. Famous for providing support for Flagr, the mobile version of MapQuest etc.
I tried to download the new Where (how much did that domain name cost?) app to my phone, but it's not supported as of yet...
Their mobile technology is sorta cool- going for the whole write once run anywhere thing for mobile apps with an xml style application definition. A location specific version of something like mFoundry. Of course, when they don't support your phone, it's a little harder to buy into that concept.
Anyway, XML as a programming language? Just because it worked sorta okay for HTML doesn't mean there aren't better ways to do it- especially when you are talking applications.
