This morning my phone took a good 45 minutes to update and when I started looking around afterwards I noticed that I no longer have the button (in the pull screen with notifications) to turn my mobile data on or off. With only 300 MB data plan I keep my data turned off unless I actually need it and now I no longer seem to be able to turn the data on and off the same way I control the Wi-fi and Bluetooth options. Why was this taken away and how can I get it back?
I had the same problem and from what I have read that was intentional. There is a app called "Data Toggle Switch" made by appsynapse that works great. It doesn't put the icon in the same line of selections but right below that. It will still be just as accessible when you pull down the status bar and cuts ALL data just as the original did.
