Hello, guys. Last time Cards app was introuced by Tim cook as new feature, I felt kind of interesting. It's sortof analog-like serivce provided by Apple. Here are my questions. 1. Is the Cards app still working on the previous iOS version(before iOS5)? 2. Do you guys really think that this service is going to work generally in market 3. I was told by one colleague that since Americans like to send a post-card as expression of thanks or congraturation to someone, this new service will go great. How do you thinks so?
