I have a 4s that I am determined to keep - not a fan of phablets and phones so big they need their own area code. But I foolishly installed iOS 8, and it is so buggy that I need to get rid of it. It's no longer possible to downgrade to iOS officially, so I suppose I need someone who can jailbreak this phone and downgrade it unofficially.
Any *specific* recommendations? I am not going to just wander the cellphone tiange and hand it over to a random self-taught technician who may or may not brick it!
