Many market research institutions pointed out that the attention received by the iPhone 3G was much higher than when the first version of the iPhone was launched. Quite a few users who already owned the older version of the iPhone also expressed their intention to purchase the latest 3G version, and all this was due to the fact that the new version of the iPhone had more advanced features such as GPS.
Despite having more functions and a redesigned body, the cost of the 3G iPhone is much lower than the previous versions of the iPhone, with a difference of about $92. In conclusion, the support of many iPhone fans combined with a lower cost will surely push the 3G iPhone to the throne as the best-selling GPS phone.
