The company unveiled more than 200 new cell sites throughout California Thursday and upgraded about 320 more sites to the super-fast 3G network.
"Our number one priority in 2009 is to continue to enhance the wireless network so our customers have a top notch experience every time they make a call, check an e-mail or surf the Internet on their AT&T device," said Fred Devereux, regional president, AT&T West.
The 3G technology makes mobile devices pretty much as useful as a laptop computer for some.
But don't fret if you're not with AT&T. Many of the other popular carriers like Sprint and T-Mobile are also are upgrading their networks to 3G.
So if you were waiting to get into the smartphone market, now's a good time to stimulate the economy.
