Yeah, i get what you mean pal. Sounds like you at least tried to be honest, although can't say i would have ! I probably just would have taken it and at least pretended to use it, too much stress to be dealing with on Christmas day.
I actually didn't say anything to her about it until a couple days after. I just left it boxed without using it. It wasn't until my Dad asked about getting it setup with the speakers (also a present i didn't need) that i told them my phone does everything it can do. Was harsh but like i said before, it's no good having which was probably £200+ worth of stuff that's not gonna be used.
