If he is asking for a 4 or 4s I am pretty sure he has made his mind that his wants to run on iOS and not Android.
I have the iPhone 4S and the battery lasts about a day, well I'm always doing stuff on it like 80% of the day, if its to check a website for 30 seconds every now and then etc.
The iPhone 4 can run SIRI if jailbroken. And I doubt the iPhone 5 will release this yr. No matter what people say, the iphone is a sweet and fancy device, I know phones such as the galaxy are stronger and shit but in reality we are not trying to run Autoposters, Uploading bots,etc on a phone so that shouldnt really be a problem.
Exactly . i am using Android from last 1 year and now time to move on iSO
Lol, why do you even consider buying an older version?
Bcos i heard there is not big difference between 4 and 4S .. just some dif like " Siri " Speed " etc...
i think i will go with 4S :d
