Hi, got my Iphone4 about 2 months ago and notice twice the data usage as with my Iphone3g. I have days of data usage with about 400MB (I was watching some hdvideos with youtube), but also for example 5 minutes of browsing pictures (no full size) in google picture search (mobile version!) generates about 5mb of data usage? Is this normal? For example I load MacRumors Forums page in Safari, hit the Todays Posts and look at one thread which altogether generates 1MB of data? Although there are no pictures? Also Maps uses a lot of data. I open maps and load a new location, zoom out so you can see the whole city which generates 10MB of Data? Within 3-4 minutes? Is it normal that Engadget/Gizmodo full site needs about 2-3MB to load? Or that a 2 minute trailer with the Youtube webapp needs 10MB of data? Thanks!
