Hi there, I've had my HTC Desire for a bit over a year now and looking to sell it so I can purchase something else. How much do you think is a fair value? My phone is still HTC Sense, debranded, SIM unlocked, stock 4GB mSD card, no scratches except for the crappy plastic covering the camera. Comes with stock box and all accessories. Back 3rd party protection skin thrown in for free. Should I upgrade to 2.2 or 2.3 before selling as a better chance of getting higher price? I'm guessing 300 EUR (410 USD)? Thanks for the input!
