iMessage allows you to communicate between the iPhone, iPod Touch, and iPad for free. With iMessage on iOS 5 you are free to chat with pictures, videos, maps, and contacts. iMessaging allows you to contact any iPhone, iPod Touch, and iPad user that currently is running on iOS 5. iOS 5 is still in beta and I cannot help you with activation for the UDID because, I do not have a developers account. Thank you for watching. Please subscribe for more over iOS devices as well as iOS 5. Please be sure to comment and thumbs up as well as follow me on Facebook and Twitter. Thank you!
