Need little or no data, 500-1000 minutes, and unlimited text. I plan to provide my own iPhone 4, I'd like to avoid a commitment of any kind. Please specify the carrier, the cost and whether or not it will work with a standard iPhone 4 out of the box, or if it will need to be jailbroken and/or unlocked to work. I am looking for cheapest possible, data isn't an issue so edge is acceptable. I also don't need sms. I don't think prepaid is what I want, based on the amount of minutes I need, but I'm open to suggestions. I live in Florida in the US if that makes a difference.
