T-Mobile let's you BYO to their prepaid side with any device that's compatible with their network. Here's the link to plans: http://prepaid-phones.t-mobile.com/monthly-4g-plans Now, this means that you need to show up with a phone. What I'm trying to do is have a T-mo store sell me a Note for full retail ($650ish) with no plan, then do the prepaid BYO option, which is the logistically easier way to go. (if they'll sell you the phone, which the one store I tried so far wouldn't) Assuming you don't talk much, the 30/100 plan saves you $50 a month compared to the cheapest plan witha similar amount of data, which adds up to $1200 over a two year contract.
Shorty seems to be going for some version of 'sign up for a contract, cancel, pay the ETF, keep the phone and sign up for pre-paid' which he'd have to tell you the logistics and numbers about.
I hadn't realize that you could do that with ETF, can you really? Shady but if it works...hmm.
