A free advice. b4 buying an iphone/smartphone know what u r buying,it's UI should meet your needs. don't buy a phone because its trending when u don't even know the A,B,C about the phone.if i were you i would have thoroughly investigated the phone(not by just looking at it).come on man u paying 2k-3k for a phone and you just take his word and walk away,no- no way.

the guy who handed you that phone sure didn't know a lotta things about the iphone.beside he must have handed u a used phone which he must have bought from a friend or something(as it was jail-broken)

lets not blindly rely on someone else belief/experience
know what you r getting when u are paying sucha lotta moeny for something
