Just passing on what I think is a pretty decent way to get a year of service AND a lot of minutes relatively cheap.

Ebay Ad has an el cheapo Motorola phone (TMFL) WITH a 200 minute/90 day pin for $19.99. So, if you have a TMFL phone, you buy 4 of these phones for eighty bucks, free shipping and you get a year of days and 2400 minutes, 2400 texts and 2400 MB and you can give the phones to a battered womans shelter or something.
