re: The iPhone is 3G EDGEis enhanced GPRS, so you argue if it is 2.5G or 2.75G, but it is not 3G as defined by the "owners" -GSM Association

re: The iPhone is 3G And in any case I don't think that many iPhone users care if their phone is 2G, 2.5G, 3G, GPRS, EDGE, UMTS, EV-DO or whatever. What they care about is a stunning user experience. It appears that with EDGE it is stunning.... Stunningly slow.

re: The iPhone is 3G 3G comes from the 3G Partnership project (3GPP - see http://www.3gpp.org), which is a whole new set of Mobile Communication Standards dedicated to be - as the name says - next thing after what is consideres 2G (GSM - see http://www.gsmworld.com) - the first broadly accepted digital globally system for mobile communication. When this got a packet data connectivity option, that extension was considered to be 2.5G; and the major update to the packet data connectivity performace is EDGE, widely also referred to as 2.75G

EDGE finally DOES improve the really unacceptably slow GPRS exprience to something between one and two times of what you were used as the Highest Speed Anlogue Model Bandwidth (56k) (or ISDN 64k) - something quite a few non- broadband home users of the internet to date do still consider as bearable for their needs (don't ask *me* why they can bear it...).

3G has two siblings based on different Radio Standards, therefore in the US there is a 3GPP2 that however with regard to many aspects of the rest of the 3G specification is seeking to us the same or even literally to copy the results of 3GPP work (which is fine - there are far too man standards out there already)

Of course as 3G gets improvments in the radio uplink performance and spektral efficiency people will use 3.5G, 3.75G for some of this, like for the evolutionary steps for high speed data downlink / uplink.

The industry would not be innovative if they would not be seeking to go beyound what exists, so the deinfition of 4G is is well underway - with the debate of which approach will make it in the wider range of markets in full bloom...
