Hello I am interested n the iphone
It is in perfect condition!  Local pick up and I accept cash only.
No cracks on the screen?
No cracks and no dings.  It is completely flawless, almost as if you just took it out of the box. 
How about the battery life? How much does it last when fully charged?
The battery life is excellent.  It will hold a charge from the time I get up in the morning around 6:30 and still be around 30% when I go to bed at 10 that evening.
