While I am not the biggest fan of the low resolution screen BlackBerry Curve 3G 9300 and 9330 this is a pretty good deal. DavidB let me know that Best Buy is running a promotion this weekend (Friday November 12 & Saturday November 13) on the BlackBerry Curve 3G on AT&T, Verizon, T-Mobile, and Sprint discounting the device to $1.
I am not sure how great a deal it is on AT&T compared to the BlackBerry Torch 9800 which is 1 penny from Amazon but on other carriers its a pretty decent deal. If you were in the market for the low end BlackBerry 6 capable phone check out the details at this link.
