it came today (in a skinny box like the refurbs do?) its a vers 0003, has a LITTLE light leakage, but manufactured 10/27/10, im assuming its a new one
If it came in a little box, its likely refurb. If it was new, it would come in the original box with all the accessories. To double check, open the Phone, and hit ##786#, scroll to Remanufactured. If it has a date there, its a refurb.
And FYI, that has nothing to do with this thread. This thread is about hardware version 4 phone. Version 2 and 3 differences have been beaten to death.
