I see these terms used on AT&T's web site and understnad that they are for internet. Can anyone tell me what is the benefit of each regarding availability of coverage and connection speed.

Okie dokie.
EDGE (Enhanced Data rate for Global Evolution)
A technology (also known as GSM++) that allows Global System for Mobile Communications (GSM) operators to use existing GSM radio bands to offer wireless multimedia IP-based services and applications at speeds of 384 kbps with a bit-rate of 48 kbps per timeslot and up to 69.2 kbps per timeslot under ideal radio conditions. (A more realistic theoretical limit is 59.2 kbps per timeslot). The 384 kbps prediction is from an International Telecommunication Union (ITU)-defined objective in the ITU2000 standard. EDGE is fully based on GSM and requires relatively small changes to network hardware and software. For example, EDGE uses the same time division multiple access (TDMA) frame structure, logic channel, and 200-kHz carrier bandwidth as today's GSM networks, allowing existing cell plans to remain intact. Formerly called Enhanced Data rate for GSM Evolution.
GPRS (General Packet Radio Service)
A Global System for Mobile Communications (GSM) initiative to deliver high speed packet data services to mobile terminals. GPRS allows many users to share the same channel and allows users to stay virtually 'on line' all of the time; radio resources are used only when data is actually being transmitted or received. Call setup is almost instantaneous and users may be charged on the basis of actual data transmitted, rather than connection time. Sometimes defined as GSM Packet Radio Service.
3G (third generation wireless)
3G is an ITU specification for the third generation of mobile communications technology. (Analog cellular was the first generation; Digital PCS the second.) 3G uses the Universal Mobile Telecommunications System (UMTS) standard. Key features of 3G systems are a high degree of commonality of design worldwide, compatibility of services, use of small pocket devices with worldwide roaming capability, Internet and other multimedia applications, and a wide range of services and devices. The main difference between 2.5G and 3G wireless is the rate at which data can be transferred. Planned rates are: 144 kbps or higher in high mobility (vehicular) traffic, 384 kbps for pedestrian traffic, and 2 Mbps or higher in fixed applications or for indoor traffic. The EDGE (Enhanced Data rates for Global Evolution) air interface was developed specifically to meet the bandwidth needs of 3G.

Phone Model: two cans ( del monte) and some string,
ATT mobile broadband- Average Download speed of 600 kbps - 1.4 Mbps burst up to 3.6 Mbps on BroadbandConnect Network
Average Upload speed of 500 - 800 Kbps on BroadbandConnect Network*
and this is directely from both companies websites
so how is sprint fastre ?
Sprint EVDO Is faster than all other service providers.
then again its Sprint. the worst cell provide known.
How do you figure? sprint has the best coverage in america. sure cs has been an issue lately but who needs cs if your product works properly? and a side note, the new ceo is working on the cs issue and sprint should have excellent cs like they used to several years ago.

best coverage?
look at the coverage map at the sprint site. then open a second window and compare to the ATT map.
