Good idea. This is definitely coming down the pipe. Not good for rim.
AT&T's Toggle lets users switch between the work and personal parts of their smartphones.
This isn't a new idea. ARM is talking about adding virtualization into the smartphone chip layer. VMware has been promising to virtualize smartphones for some time. What is notable about AT&T's technology is its flexibility. VMware's technology hasn't hit end users yet, largely because it must be pre-installed by phone manufacturers, limiting it to carriers and device makers that want to install it on their hardware.
AT&T's "Toggle" technology, meanwhile, works with any Android device from versions 2.2 to 3.x, as well as iPhones, and can be installed after a user buys it. Moreover, the technology is somewhat separate from AT&T's cellular division and can be used with any carrier.
