AT&T is trying to address the needs of all those who are concerned (or trying to cope) with having all their business or work related stuff on the same phone with their personal content, such as games, videos, pictures and music.

AT&T Toggle tries to offer a simple way of switching between work and play. There’s a Work mode with corporate email, applications, calendars and more and there’s a Personal mode where you can send text messages to friends, watch TV shows and movies, and play games. Toggle can be used with Android 2.2 Froyo and higher, and with any service provider, with availability expected before the end of 2011.
