Bump CEO Dave Lieb took some time to chat with us in the VentureBeat studio recently, and we talked all kinds of trash.

Bump is the mobile app that lets you send data back and forth between two phones simply by physically “bumping” the devices against one another. A common use case is sharing contact information, but all kinds of files can be transferred this way.

First, we noted that Bump’s core value proposition has become a feature in Google’s latest Android release, Ice Cream Sandwich. Lieb’s take is that the move isn’t surprising, but flattering — he sees the ICS feature as validation that the Bump team is working on a legitimate solution to a common problem.

We also talked about the app’s wild popularity and about the startup scene in Chicago, where Lieb & Co. started out, themselves.
