Update my software

Assuming you have a compatible device, see: Update your iPhone, iPad, or iPod touch - Apple Support

And: If your iPhone, iPad, or iPod touch won't update - Apple Support If the above Apple articles do not help, please post back with relevant information. 

You've given us no information to be able to help you.

1. What iPhone model do you own?
2. What it its current iOS version?
3. What iOS version are you hoping to update to?

Provide those details and we can then help you.
