Dang. That's a killer deal on the T401g. I ordered one.. I have a 200 minute and 300 minute card from the old bundles (along with whatever free phone) so I'll hang onto them and use them on the refurb'd T401g if the need arises. The $25 750 minute plan is a nice alternative. It might not be the most competitive but it's good for people who are accustomed to TracFone/NET10, and it will only encourage more and more choice in the prepaid market.
Their ToS say that you can't switch between the traditional pay as you go plans and the monthly plans, but I see their FAQ says you can. I guess the only way to find out is to actually try it, but I'm inclined to believe you can only because they're touting how you can choose what fits your needs and how the 300 minutes isn't included anymore so you can choose what you want, like their monthly plans.
Castrol EDGE 5W-30 is my drug of choice.
