Will T-Mobile iPhone 5 work with $30/month plan?

I'm on Verizon and thinking of switching to T-Mobile since their coverage is good in my area. Does anyone know if Apple or T-Mobile will be selling the TMo iPhone without signing up for a new plan? I'm thinking I can offset the cost of the phone by signing up for the $30/month prepaid plan since I rarely use the phone to talk.

Any insight would be appreciated.
