Planning on heading to T-Mobile to pick up a free phone at their huge Father's Day sale this weekend? You'd better bring your wallet with you. TmoNews has a chart showing that all phones at T-Mobile will be free after rebate, along with what you'll be paying in store for your new device. When looking at the chart, "POS Amount After Price Override" is the amount you'll be paying in the store and "Promo Retail MIR" is the mail-in rebate. While you won't be paying more than $100, it's disappointing that customers will be forced to shell out cash and then wait for a mail-in rebate to come around. However, most consumers are accustomed to mail-in rebates, and you're still getting a free device, it just won't be free right away. Besides, if you're really that peeved about dealing with rebates, you could always head to The Shack and get a free phone on a single line with no rebate or activation fee. So, who's taking advantage of the sales and getting a new device this weekend?
