Although AT&T has a full HSPA network which was prepared in time for the launch of the iPhone 3G, that doesn’t mean it couldn’t be upgraded to 4G. AT&T seems not to be interested in 4G as it says it’s willing to wait at least two years, if not longer, until it would start deploying the next-generation network

Hank Kafk, AT&T’s vice-president of Architecture said at the 4G Executive Summit that AT&T’s current 3G network already offers more than Verizon EV-DO network. While waiting for future AT&T LTE network we might see an actual speed increase of the current 3G network. AT&T wants to offer subscribers a HSPA+ 3G network which will come with speeds of 20 Mbps sometime next year. Future 4G network might be postponed anywhere from 2 to 5 years.

But why talk about 4G networks when there aren’t any phones specifically created for them?
