Bro,

One of the weaknesses of iphone be it 2G or 3G is that it cannot be used as a modem like the Nokias or the winmobiles for net surfing or internet sharing on the winmo. So if you plan to do so and use an iphone, you might be dissapointed. However you still wanna the iphone, then get an external modem like the Huawei but still use the same line.
