Before Apple had quietly made this change, iPhone users could only download applications 10MB or less. Unfortunately, with the AppStore growing rapidly with far greater apps, 10MB was just too small to download them on-the-go.
Luckily Apple have seen more sense to enlarge this given limit by doubling the previous allowance to 20MB. This still may not be enough, but it should do for the necessary applications which usually rake in at about 15MB.
Better games now rake in at about 100MB to 200MB, and some increasingly larger. There’s no doubt that Apple could have risen this limit for their coming of the iPad, which applications will require far more memory to perform on the big screen.
Mobile network providers may not be too happy with this decision, but it’s great news for the average iPhone user.
