iPhone App communication using phone numbers?

Is it somehow possible to use phone number of receiver to send app messages?

The idea is the user don't have to know anything about ips, etc. just a phone number. Then the app can find this user and send messages (app protocol).

Sorry complete newbie question, bu开发者_高级运维t was just wondering if there's a connection… I didn't find any information with search engine…

Yes, you could do this, but it would require both parties to have your app installed and you would likely need to create some sort of intermediate web-based service to store their account information (username, password, phone number, UDID, etc) then use that service to send the app messages from the sender to the receiver.

Assuming both of these users would be using an iPhone it will probably just be easier to wait until iMessage is released with iOS 5 in a month or two since it will work similar to FaceTime in that you can use phone numbers, emails, etc and works between all iOS devices running iOS 5.
