Just a quick question, really.
When I'm tethering (via USB, or wireless, or whatever) my phone's apps (and there are a significant number of my apps which do this) are constantly using the phone's mobile data connection to push notifications.
My phone's mobile connection is poor at the best of times (Samsung Galaxy S3 on o2 in the North East of England), such as now, where it's constantly flicking between G, E, H, H+ and 3G.
As such, I'd like to effectively "disable" my phone for every purpose other than providing an internet connection my laptop via USB or wireless.
Is that possible?
