Chosen Solution
I have an 8GB iPhone 4s (model confirmed by the tool on this site) and I need to change tś battery. In all guides and documentation I can find on the site I can choose between 16 and 32 GB. No 8GB choice is avaliable. Does it matter for what I need to buy, and for the process of changing the battery?
tobiasaheiberg, no it does not. The battery is compatible with all models.
