A new survey reports that the iPhone 3GS has been successful due to the fact that the iPhone continues to be innovative and its customers have stayed loyal to its manufacturing company, Apple.

According to the survey which was conducted by the BC/IQ ChangeWave polling company, over 99% of iPhone customers said that they were ‘satisfied’ with their mobiles and an additional 92% reported they were ‘very satisfied’ with their iPhone 3GS mobiles.

Among the most appreciated features on the iPhone was ease of use for third party applications and its touch screen interface.

The negative reported features of the iPhone include its short battery life, the exclusive contract with AT&T as a network provider, and the lack of support in users’ IT departments for the iPhone.

The survey also found that 41% of the people who purchased the iPhone 3GS previously owned the prior model.

Those who purchased the iPhone 3GS for the first time split down the line with 18% switching from a Motorola device, 11% from a Nokia mobile, 6% from a Palm mobile, and 8% from a Sanyo mobile.
