at&ts edge network is usually qualified as being 2.75g
there is edge evolution out there too. but lets just say...
no, there is no 3g with at&t. no 4g with at&t. nothing beyond edge.
i switched to tmo just for 3g and i will save around $1800 over the next two years on my will and i have an even better plan than with at&t and no contract
