D600 is ace mate, doesn't do anywhere near as much as the N70, tho its small, looks good, 2.0MP cam, takes transflash memo cards and is probs a little cheaper than the N70.....
I got my brand new D600 from ebay....sealed box, unlocked and unbranded for £260 posted.....tho the phone really only cost me a 10er as i sold my k750i that was my free vodafone contract handset to my brothers mate for £250...
IIRC the D600 is around £400 sim from out of the high street stores.
