I think the real use is to let u still be on wifi and have Internet access through your phone instead of the wifi network. That's not possible now. If I'm on wifi and the network has no Internet then your phone can't do shit online
Here's some real insight. Wifi Cellular is apples way of moving away from implemeting something like SBSettings on the jailbreak side. No need tonnage wifi/3G when whatever ur doing on wifi starts to stall. Also Bluetooth pairing is integrated into the media controls, one more reason to ditch the Bluetooth toggle in SBSettings. Thoughts?
I think this move is really trying to do what bbm has. Cellular over wifi .. Think about it. On my bbb I can make a call via wifi from the phone app if I have no service.. Apple I think is moving into this direction. Couse bb does all this already.. Yes it's as similar as 3GUnrestrictor. So yes aPple did yet again steal another JB idea to make a fool and show bb how it should be done..
This isn't really new news. Because we all saw the thread that states ft over 3G instead of wifi. This paved the way for the above news and will for many more. The only issue with apple making everything able to use data and not wifi is that the data will rape u
