My new month starts Saturday, so it won't be a huge problem. But if you call and I don't answer...that's why. Leave me a message and I'll give you a call back from a phone that *won't* charge me 40 cents a minute (the overage rate).
Although on a humorous sidenote, my current minute usage for this month (as of right now) is 573. If you get that, you are a nerd...but you are also likely chuckling right now as well.
