This is something I thought of and I think this info may be useful for someone out there... I won't do it myself since I don't know how to flash phones but for someone who knows how to flash a phone, it could be very useful for you.... Step 1: Buy a phone that was popular but has been replaced with a better phone. I would say the Samsung Galaxy S2. You can get that phone for cheap now a days depending which site you buy it from. I seen one for Sprint that was $29.99. Step 2: Flash the phone to a carrier that never had the phone. Suggestion, Flash that S2 phone you bought to boost Mobile (or MetroPCS is another good one) Step 3: Sell on ebay and profit. I see people selling phones that are flashed for $250.
