The iPhone 4S was actually released not very long after the original iPhone 4 was. This device is similar to the original, it's very boxy, it has all of the same buttons as the original and it has a very large screen. The iPhone 4S is one of Apple's most popular iPhones, but the screen can easily break, crack, or become damaged. If you need touchscreen replacement, then we provide affordable solutions here at The iPod Repair Centre. IPhone 4S touchscreens normally get broken when they have been dropped on the front side. However, you can also drop the phone on its backside and this can affect the front side of the phone. The screen can get cracked relatively easily, so you need to look into iPhone repair services if this has happened to you.
