If we compare the handsets closely we find a lot of points that make these two gadgets different from each outer. The first difference that is notable is the screen size. iPhone has a 3.5 inch TFT capacitative touch screen and the iPad has even larger screen measuring 9.7 inches. Obviously, the resolution of the latter would be better, which is 1024 x 768 pixels whereas the iPhone brings out 640 x 960 pixels of resolution.
Both the handsets are capable of running on 3G network. So the connectivity is superb in both of them. The operating system used by iPhone 4 is the iOS 4 whereas iPad uses iOS 3.2. In operating system iPhone beats iPad. The Apple babies use Apple A4 processors. This is the reason for the tremendous speed that they provide.
There are various deals available in the market that are offering Apple iPhone and Apple iPad at cheap rates. But iPhone 4 Pay As You Go deals and iPad Pay As You Go deals are doing a fantastic job. Both the deals are gaining more and more popularity.
