dude you are asking a bit high , i saw a FACTORY UNLOCKED 3GS 32 GB (WHITE) sell for 52k exact in the market.
if its factory unlocked , you might be able to sell it in this range , but if it is not , m afraid 46 is the last you should expect.
BTW this was the Karachi market , maybe Lahore market is a bit higher...
apologies if i offended you.
