I read a PC Advisor article that said genuine Apple batteries are available in the UK on ebay (+ a guide to install them). http://www.pcadvisor.co.uk/how-to/apple/3346693/how-replace-iphone-battery/ Has anyone had any experience with any ebay sellers in the UK selling these. Are they really genuine? for example : http://www.ebay.co.uk/itm/IPHONE-4S...K_Replacement_Parts_Tools&hash=item2322f7c40c The description says : "These batterys have been dissasembled from the brand new iphone 4S phones" I wonder why you would take the battery out of a new phone rendering it useless and sell the battery for £8. Yet they have 99.8% positive feedback from 6000+ people.
