this is my position, I pay $225 a month for the service on my phones. all 3 phones combined we use less than 3Gb a month in regular service.
If I want to root my phone and use WiFi tether, then I am gonna freaking do it. And I BEG them to try and stop me. NO jury on this planet would find against me. Apple lost their lawsuit about voiding warranties on iPhones that are jailbroke, so therefore the precedence is set, and they threaten everyone over everything anymore. FIX the service so more than just a couple of markets have 4G then I would not mind paying extra, but since I will never see 4G where I am at, they can kiss my WHITE, TAX PAYER ARSE!
