I KNOW I MADE AN IPHONE 4S REVIEW. That iPhone isn't really mine... Well... In this thread please don't ask me to get another kind of phone. Thanks Let me start off... I have an iPhone 4 16GB and I feel like selling it now and get an iPhone 4S instead. I worry that when the supposed 5 comes out, the 4's value will drop down the deep shit. (it already dropped like $300 when the 4S came out) As of now, my iPhone 4 can be sold at about $400 - 550 to retailers. A 4S 16GB costs $900 - 940. Should I keep my 4? Or sell it to get a 4S? I have some spare cash which I can use. I can get a new iPhone from my carrier by the end of this year but my current phone is already out of warranty and has 'not too good' battery life. Either way, it's mainly about retaining phone value. Headache >.< Thanks in advance.
