Apple may offer a 3G version of its iPhone in Europe by January 2008.

A report on AppleInsider cites sources at a Swedish firm who claim the first-generation iPhone would arrive as soon as September with a 3G follow-up model potentially making its debut in January 2008.

The first version of the iPhone ships in June in the US. This model offers support for EDGE networks, but not for 3G. EDGE is a type of high-speed wireless that is widely supported by US carriers, however in Europe many carriers have made significant investments in 3G.

Launching the iPhone in January, Apple CEO Steve Jobs alluded to 3G support as a potential improvement for the future of the product.
