Hi Friends Here am again with a review of a Iphone 4s. I am using this phone last 3 years. wifi is not working last 2 yrs. in cellular network software never update so my software version is still old and I can’t update it. And guyz over heating huh! You can fry a egg on my phone and main thing is that you can’t do anything because if you take it to iphone care they restore it and you loose ypur data and again and again cycle repet. So if you are going to buy Iphone 4s please make sure . This is my opinion do not hate iphone 4s use it experince it. Allah Hafiz
