We currently have a family plan with 5 lines. We have the family plan for messaging.

I have a smartphone, my son has an iPhone and my daughter is about to get a smartphone.

I would like to see a family data plan that allows all users to share a bank of data, ie 1GB, rather than having to purchase a seperate data plan for each phone. I use very little data but my son uses more. I have a lot of unused data each month. A bank of data would allow the data I don't use to be available to the other lines.

A pricepoint of $30-40 for 1GB shared seems fair to me. (based on $15/200MB per phone I'm paying now)

Good idea? I think so.
