I guess you could call it 0G 1G was the first version of digital, using CDMA and TDMA. Some phones were data capable but it was very slow. 2G was the second version of digital. TDMA was replaced with GSM (which uses TDMA but it’s incompatible) and it had reasonable speed data, EDGE and 1xRTT. 3G is the third version, with UMTS replacing GSM (using a CDMA air interface). High speed data appeared including HSDPA and EVDO. Like the original iPhone, the 2G name only came about when the term 3G was coined. Some phones were considered 2.5G since they were partway there. 4G is LTE or WiMax. Analog is separate. I guess you could call it 0G

Let's hope we catch up soon! =) While I’m not entirely sure I want people talking on their phones in the subway – it’s bad as it is already – I would love to have a better mobile network that allows access to richer media.

It's slightly better here in the UK, but not as bad as the USA (which had always surprised me). Great article, makes me even more jealous of the technology available in Asia!

Its not the network, or the handset, but the video conference server at the telco mixing 4 low quality video and audio streams and dialing out to a user with or without a face aimed camera. A premium service you have to subscribe to. Advertising is wonderful at creating demand. "Sorry son, couldn't get in touch with you until you got to the fish market."
