If you call GPRS 2G, then Edge is 2.5G, then 3G is 3G obviously. Then no data network at all would be 1G, which is purely voice and text.

GSM itself is inherently a 2G technology at a minimum.

1G wireless technology is analog (rather than digital) service -- mostly AMPS in North America -- and it was voice only, no text messaging.

The immediate successor to AMPS, D-AMPS (also colloquially known as TDMA, although several other technologies such as 2G GSM were also inherently TDMA), was used for a while in the USA before carriers moved on to either GSM or CDMA-based services. D-AMPS was a digital service that provided features such as text messaging, and it is also technically considered to be a form of 2G network.

AMPS has been switched off for several years now (so has D-AMPS), so no phone currently active anywhere in North America would ever be able to legitimately report being on a 1G service.
 
H normally stands for HSPA which is just a combo of HSDPA + HSUPA which both ATT and Tmobile 3g networks have.
 
I'd like to see them add a + in some form or fashion for my own information. I don't care whether it is 3G+ or H+, but I'd kind of like to know when I'm allegedly getting faster data speeds! I'd like to know what portion of my region has that sort of coverage.
 
The reason those android phones show H+ 100% of the time is because AT&T's mobile broadband network is fully covered by hspa+. However, only in areas of enhanced backhaul are where you'd see "4g" speeds.

Exactly. So you will see H+ or whatever it is but you won't know if it's upgraded to fast data speeds or just regular 3G.
In other words it's all a marketing gimmick IMO.
