Today AT&T begins selling an interesting new GoPhone pay-as-you-go option, offering users unlimited domestic local and long distance for $3 a day, only on the days that you use it. If all you need is a sheer crapload of voice minutes, this actually stacks up really favorable against AT&T's postpaid offerings, which price unlimited service at $99.99 a month -- with this, you'll be paying between $84 and $93 a month, assuming you end up springing for service every single day. Of course, the tradeoff is that you're stuck bringing your own phone to the network or picking up one of AT&T's GoPhone devices -- which tend to dominate the low end of the spectrum -- but then again, if voice is really your thing, odds are you don't care about how many accelerometers your phone features.
On a related note, Samsung's a177 (pictured) has gone live on AT&T's site, bringing a solid text messaging experience to the prepaid market. As you might expect of a $99.99 no-commitment phone, all you've got is a VGA cam -- but roughly $110 a month for unlimited contract-free voice and texting on a top-tier carrier might be enough to sway a few in the a177's direction, assuming value leaders like Boost, Cricket, and Virgin Mobile aren't picking everyone off.
