My company built a web-based Twitter application to embed to phones. We are going to contract to phone manufacturers and agencies.
There's no advertisement. Our application is going to embed to phones. User's don't pay about using it. 1. Should we pay to get a commercial API key or pay them? 2. If we pay, How much traffic can we use? We need infinite traffics. 3. What legal issues about using Facebook application name and icon? We are using name "myTwit", and newly designed icon.
