www.WirelessFederation.com/news: The size of the iPhone downloaded over 3G has been boosted by Apple from 10 MB to 20 MB. Earlier, users downloading an app larger than 10 MB had to switch to a WiFi connection. The reason behind the limit was to preserve the bandwidth. It has been speculated that Apple has made the change in anticipation of the iPad, which is set to debut in late March. The typical iPhone apps populating Apple's App Store will not be as large as iPad application downloads. iPad apps will have to support higher-resolutions graphics due to its 9.7-inch screen, especially for games. It appears iPhone users will be able to enjoy downloading larger apps while on the go using 3G.
