Problems updating to ios 5
This has fixed the issues surrounding i Message (and Face Time, too).
In order to do this, go to Settings → General → Date & Time and toggle the switch on Set Automatically to ON.
Facebook was integrated into the operating system, incorporating status messages, like buttons, and contact and event synchronization to several of Apple's apps.i OS 6 is the sixth major release of the i OS mobile operating system developed by Apple Inc, being the successor to i OS 5.It was announced at the company's Worldwide Developers Conference on June 11, 2012, and was released on September 19, 2012. i OS 6 added a new Apple Maps app, replacing Google Maps as the default mapping service for the operating system; a dedicated Podcasts app, as a central location for podcasts; and a Passbook app, for managing different types of tickets, boarding passes, coupons, and loyalty cards.Now, reboot your i Phone, turn on the Wi-Fi/Cellular and try to send i Message again.If the first trick doesn't work, then Reset Network Settings.
i Message may not work if there is poor Wi-Fi or cellular connection.
