Those of us in Ye Olde United States often still have 2.75G (EDGE) cell phones at best; only you fancy Europeans and Japanese have 3.5 or 4 or whatever you're up to nowadays.

N.B. In the UK at least 3G coverage, and/or adoption, is still sparse to non-existent; leaving 2G and 2.5G, GSM phones the most common portable telecommunications standard. This is also true for Australia, especially the cheaper pre-paid phones.

And still the case in Finland, home of Nokia.
