Because I'm on T-Mobile's cheapest plan which is the 500mb data plan. Each time the OTA downloads it eats up 155mb. And twice already this billing cycle it's done it, so that's 310mb of data wasted.
There are posts saying to use Titanium Backup Pro and freezing an app called Software Update MUC, and another post referring to the file as Software Update 18.104.22.168, but on my phone (using TB Pro) there's no file starting with "Software" anything.
So how do I stop my phone from downloading the OTA all together? Please help. Thanks.
