I have an iphone 4S running iOS5. I get reminders to upgrade to iOS6. If I do this, will my Google Maps Apps be replaced by the Apple Maps app? If so, can I get my Google Maps app back?
My particular field of expertise is iOS Jailbreaking and Unlocking.
If you're referring to the Google Maps app that you download from the AppStore, no, that will not be replaced. You'll have to re-load it back on your device through either a backup that you've made prior to the restoration of the iOS, or you can simply re-download it again through the AppStore.
