Ok, don't hate me: I totally sold Cydia to Microsoft, and am now working on a .NET to Objective-C connector with the eventual goal of porting Silverlight.
Apparently, Microsoft has a booth here at CTIA, and Bill Gates decided to show up in order to make the deal himself: he feels they need this to compete with Apple's mobile strategy.
I'm not exactly certain what this will mean for Cydia, but I'm certain that it will be positive: probably a new look based on Aero and integrated support for VBScript control files. I'm excited!
