How to make my iPhone update?
I'm pretty sure it's an iPhone 3GS; my mother's boyfriend gave it to me after he got a new phone. Of course, the service was cut off, but it still works on Wi-Fi. My mom's phone is the same model, and the service is cut. She still receives updates and stuff. Before the phone was given to me, Joseph reset it back to factory default. Now, every time I go to download an app, it says I need iOS 4.3 or iOS 5.0. Or some other iOS. How can I get it to upgrade?
