If I send bring my used Iphone 4 to apple, will they allow me to upgrade to an Iphone 4s
I have recently purchased a Iphone 4, off of Kijiji. I use my own personal Itunes, and the phone is in good condition. (no cracks, minimal scratches). Also, after I purchased my phone, I noticed the volume does not reach the maximum. Although it says it does, the speakers aren't as loud and clear as other people I know, who have an Iphone4 aswell. I was wondering two questions, If i were to bring my Iphone4 to Apple, would they fix the volume issue? also, If I wanted to upgrade to an Iphone 4s, perhaps if I traded in my Iphone and payed around 100$, would they sell me an Iphone 4s? Please help! 🙂
Sincerely,
A Confused Iphone User.
