For those with iPhone contracts, AT&T offers free iPhone Wi-Fi at hotspots on their network. There are thousands of AT&T wireless Wi-Fi locations nationwide. Connecting is easy and will incur no charges on your wireless bill.
Start by searching for a local AT&T hotspot, or entering your local Starbucks (most locations provide AT&T Wi-Fi access). You can find a map of available AT&T Wi-Fi locations on the AT&T website.
