HTML5/Cross Platform mobile-app (simple contact list converter) by chrislee

I’d like to write a simple mobile-app. Preferably in HTML5. You can either develop app in native-environment for each device or you could use something like Titanium SDK or PhoneGap to develop a cross-platform app… (Budget: $8-$15 USD, Jobs: Android, Blackberry, HTML5, iPhone, Mobile Phone)
