Replacement battery iPhone 4s
Can anyone advise me where Can I get a GENUINE Apple replacement battery for an iPhone 4s?
I am and electronics engineer and well qualified to fit my own battery. I am reluctant to use a 3rd party battery or let Apple charge me ÂŁ70 to do a 5 min job. The Apple store in Sheffield say take it to a retailer and let them do it (ÂŁ70), but they won't sell me the battery. The Phone is out of warranty.
Thanks
