Where can I get the info on iphone 4 upgrades?

Hie…iPhone will not come in any update now as it has launched a new phone and that is named as iPhone 4S, which is equipped with more powerful processor than its predecessor. Look wise, you will find iPhone 4S a almost same as that of iPhone 4 but apple has come up with a lot of improvements in the phone. The phone is having iOS 5 which can work faster than that of iPhone 4. It is having i5 dual processor in the phone that means phone can web pages twice as fast, applications will launch and run faster, data will download twice as fast and graphics will render faster 8MP camera is able to take photos with a great clarity. I think this is the best phone we have right now in the mobile market. Thanks
