Im waiting on my upgrade Iphone 5. In the past i have always got USB chargers off ebay,they always worked perfectly and were much cheaper than buying from apple. With new style of USB cables.Will the cheaper versions from Ebay still work? 1s like these? http://www.ebay.co.uk/itm/Brand-New...ories_MobilePhoneChargers&hash=item43b5428f5a Reason im asking is because i heard there was a chip in the new chargers?
