Me and my friend had a sleepover, we have the same phone and charger, but mine are brand new. and i could of sworn the charger she took was mine, because mine is brand new and it definitely was the rounded wire one, but she says no it's hers. I am so frustrated because it's definitely my charger, and i want it back, it's new and its mine. QUESTION: Should the RIM PART NO: HDW on the back of my charger, be the same as the HDW number that is on my phone when i take the back cover off? Because the numbers do not match. Should they?
