T-Mobile is allowing qualified customers to purchase headsets and accessories in four-month interest-free installments. You know the economy is bad when you are buying cellphone cases in installments.

The Equipment Installment Plan applies to both current and new customers and comes without any additional finance fees, interest charges or start-up fees. So, if money is tight but you have been dying to get your hands on a G1, this might be the way to do it. [T-Mobile]
