Hey guys! Like many people who just found out about the new limit on the iPhone, I am wondering what 2gb of data really is? I'm planning on buying a 4g but I want to make sure I won't be going over the usage every month. I am young and use the internet a huge amount (thankfully I'm on a college campus and will mostly be on wifi). But what is 1 mb of "usage" ? I am a newbie...I am good with computers/phones, but I don't understand the whole usage thing. If I watch a youtube video and download a new app every day, will I go over 2gb of data? Does the iPhone download a youtube video to watch it, or is a youtube video normally just 1mb? The new iPhone will have a higher res screen, meaning higher grade streaming....will I go over it? And what about videochat? Would videochat easily suck up 2gb of usage over 1 month? I don't currently have an iPhone and therefore cannot really go online and check my usage. Any information would be much appreciated!
