had my 8 gig iphone around a month or so now brand new. Over the last couple of days it seems that its not charging correctly. Been charging using the PC and left it charging for a few hours (5 or so) the bat shows full. but i've come to the phone again this morning after not using it since its less than 1/2 full 
going to give it one more try this time using the mains, but if that fails what options have I got now there's no 8gigs about. If I take it back to carphone warehouse will they just refund me the money or can I hold them to a new iPhone and get them to give me a larger model thats in stock or even a v2 if I hold out a few more weeks, or will they force a refurb? don't fancy a refurb as its only a month old.
