Im still using my 3GS and am reasonably happy with it. It’s out of warranty now though, and it slowing up. The camera is rubbish too. So – is the 4s worth it? Not bothered about Siri tbh, and I’m not interested in another manufacturer either. All input welcome!
Big step up is from 3GS to 4. 4S is marginal improvement over 4 in terms of camera resolution (better) and processor speed (not noticed this at all to be honest). 4S is way worse in terms of battery life compared to 4.
I recently went from a 3gs to a 4s, it is noticeably faster. The display is sharper than the 3gs as the 4 and 4s have retina display. The camera is 8mp and can shoot HD video and also HDR photos… I think the 4s also has a better camera lens, the quality of photos are alot better. Other than that no real difference in day to day use (I don’t use Siri).
