I have been researching into the possibility of hacking into the Iphone 3GS and the result is worrying. For those people who are using it as a tool to provide protection over their files will have to take note. The Iphone 3GS does provide users with a simple protection but other than that, it is as good as your normal phone. I don't see why governmental organisations are using the Iphone 3GS as a tool in thinking that it is very safe to use.
I have read reports stating that the earphones on the Iphone across the range (2G,3G and the 3GS) will produce slight electromagnetic shock to customers and the Iphone 3G and 3GS have SAR value of more than 1.33. I don't think it is wise to use them as a tool to receive and to make calls without using a bluetooth headset.
Look at the Nokia 5800 XpressMusic for instance. The SAR is less than 0.70! Can't you see the advantage of it? It will not damage your body as much as the Apple Iphone!!! Think about it.
