iOS blinkup app on iOS 3.1.3

I was wondering if the iOS blinkup app could be made to run on iOS 3.1.3, and thereby support the first generation iPhone.

The reason being, that I and many others, have old iPhones lying around, and they would fit nicely in the imp lab.

We can’t, no. The current iOS SDKs don’t allow you to build apps for anything before iOS 4.
