Apple iPhone 4 is a fantastic device, which provides hotspot feature not offered in AT&T’s device. It is basically a touchscreen slate smartphone designed and engineered by Apple Inc. It is now in its 4th generation and a successor to the iPhone 3GS. The iPhone 4 is especially marketed for video calling, for general web and e-mail access and consumption of media like movies, books and periodicals, games and music. It was announced in the month of June 7, 2010, at WWDC 2010 held at the Moscone Center, San Francisco and was revealed in June 2010 in United Kingdom, United States, Germany, Japan and France. It runs iOS operating system of the company, the same OS as used on previous iPad, iPod Touch and iPhones. It is primarily controlled by user’s fingertips on multi-touch display, which is quite sensitive to fingertip contact.
The most visible difference between predecessors, and
Apple iPhone 4 is the new design that integrates uninsulated stainless steel frame, which acts as its antenna. The internal components of the device are located between two panels of chemically strengthened aluminosilicate glass and features 512 MB of eDRAM as well as Apple A4 processor, twice that of its predecessor and 4 times that of original iPhone. Its 89 mm liquid crystal LED backlit display boasts 960 x 640 pixel resolution and is sold as Retina Display. The latest OS release is iOS 5.0.1. In 2011, the iPhone 4S was announced that retains the same form factor however integrates some updates like iOS 5, enhanced camera and A5 processor.
The Apple iPhone 4 has much in common with its AT&T counterpart, but different performance and varying features provide it enough room for standing apart. After nearly 4 years of endless gossip, so-called leaks and analyst forecasts, the Verizon iPhone is a reality. Like its predecessor, it entails quite a few serious give and take on the part of a user. The network of Verizon provides discernible enhancements over AT&T’s. The data speeds are even faster. The iPhone 4 is available for the price of $199 for 16GB and $299 for 32GB model. It measures 4.5 inches high, 2.3 inches wide and 0.37 inch deep and weighs 4.8 ounces. The iPhone 4 has almost similar features such as gorgeous Retina Display.
Turn the
Apple iPhone 4 on its sides, and you will find quite a few minor enhancements. For accommodating CDMA antenna, the ringer mute button on the left hand side has been moved little closer to volume controls. Inside, Verizon provides some differences, both bad and good. It allows creating a connection via Wi-Fi, USB cable or Bluetooth and or using all three methods at the same time. Once you are set with Verizon, the hotspot option will appear in your Settings menu. After you set a password and select which connectivity options you would like to use, you can get started.

The introduction of iOS 5 makes it even superior, but if you can afford the additional expense, then it is worth at least considering better iPhone 4S.
