I have got a jailbroken iphone 4 running ios 6. I want my wifi and cellular data settings to be on, but I want certain apps to use wifi or cellular data. The issue is that I always use my iphone to write emails, brows the internet, or work on a couple of other apps that need wifi. However, while working on those apps, I do not want to receive imessages, whatsapp messages, and I do not want any body to call me via line, viber, tango, rebtel, forfone, etc. And I do not want to go to the seetings of each of these apps to change status from on to off or vise versa from the notifications center or block all contacts or do any of this hectic work. I expect there should be a tweak that allows me to decide which apps can have access to wifi and cellular data and all I have to do afterwards is with one switch from the settings activate this function or deactivate it. Anyone knows how I can do that? Thank you in advance.
