I started looking at the T-Mobile small business plans today, and those are crazy cheap! Unlimited data, 5GB tethering, unlimited talk & text, 5 phones, for only $110 a month. Also T-Mobile is talking about how they will pay user's ETF if they switch, but they have to trade in their old device. Do any of you know if there is a requirement for the old device? I'm currently on AT&T with 3 iPhone 5s, 1 iPhone 5 and 1 iPhone 5c, none of which I am willing to trade in. If you just have to trade in a phone, would I just be able to purchase some used Motorola Razr v3 phones and trade those in? I just ordered my T-Mobile test drive device today and am excited to try the service. If all goes well I think switching could be a possibility, but I am still in a contract with AT&T. How could I get my ETF's paid without trading in all of my iPhones? Also, would AT&T unlock the iPhones once the ETF is paid so I can then use them on T-Mobile?
