I was wondering how this works? do we just automatically get the free 25 GB of dropbox storage from an app on our phones? I was reading that anyone who buys an HTC One device will be able to take advantage of this and since im planning to buy the One S this is something that interests me. Also will count towards the limited amount of data we get? since we are sending media information im afraid that this will completely use up any data plan and I will accumulate additional charges. if this is so then its not worth using.
