Ok so basically here is the deal; I currently have an iPhone 3GS and plan on getting the Samsung Galaxy Nexus. I want to know if this is going to affect my phone carrier data. I have AT&T's unlimited data plan from way back when it actually was unlimited, and I refuse to use their new plans so I'm getting this right out. Apart from throttle my data at a certain point, will anything happen that will cause them to try and bully me into changing plans? I would greatly appreciate an answer that isn't based on guesses, I'm looking for assurance based on experience.
