AT&T is a network and they do have a 3G network. They are not considered a 100% 3G network because they have a lot of different options.
Att
I believe Verizon Wireless - they do have better coverage (probobly), and does have "The Largest 3G Network". Hope i helped.
i get 3g on my iphone there from att
I doubt 3G will be free on PlayStation Vita, however you can use WiFi on it free of charge (besides paying for the WiFi bill as you already do). No it is not free you need to have an ATT internet contract. The 3G model is $300 and the WiFi Model is $250 both still require purchase of internet service and the 3G is exclusive to ATT. The PlayStation Network (PSN) is free once connected
i777 is not physically supported by tmo's 3g/4g network and it will just stay at edge.
iPhone 3G by far
Well you would using the Edge network not the 3G so yes It would be a bit slower.
No we can't use different network 3G sim in Vodafone 3G sim.
The iPhone 3G is capable of accessing a 3G network. Some of the older iPhones and the new iPhone 4 can not access a 3G network, however. There are many droid that have the same applications as the iPhone but that will hook up to the 3G network.
