Generally speaking, WiFi access, at least at home, will always be faster than your iPhone’s 3G connection. However, connect with WiFi hotspot at a coffee shop and you know the speeds can be anything but palatable. Apple is well aware of this conundrum, and realizes that toggling WiFi on and off to simply access your iPhone’s cellular data connection is holy impractical. The result? Something called WiFi Plus Cellular, which was recently discovered in a developer version of iOS 6.
Much like WiFi can be toggled on and off, so can WiFi Plus Cellular. When it’s enabled and you happen upon a congested network, or suddenly experience a bottle neck in bandwidth, your iPhone will automatically reroute the pipeline and begin to suck down data from your cellular plan. And for those of you concerned about blowing through your monthly allowance, it looks like you can choose which apps have access to this feature, hopefully eliminating a hefty monthly bill.
