Hi all. I have unlimited Internet on my iPhone so downloads are not an issue. But if I try and download an app that is over 20mb it will only do it via wireless. This is ok if I'm at home, but if I was out and about I'd have to either not download it or try to locate wireless somewhere! So this make the iPhone not as portable as you'd like. Is there a way at all to bypass this so I can download apps over 20mb or is this what apple have built into the phone?
