UK GNex owners. Let's sell up...
Asda are offering a guaranteed £150 for a working GNex.
If you have a spare phone you can live with (mines a cracked HTC Desire) while you wait for the N4 release, then you'll be getting more than half the cost of the phone covered.
Then move to giffgaff for £15 a month and get unlimited data.
Cost of this for the equivalent of a 2 year contract:
(£15*24 months) + £289 (for 16gb N4) - £150 (for Gnex) = £499
That is crazy cheap!
