Hey guys
A friend of mine recently upgraded my iPhone 4 to iOS5 and the facetime icon is missing.(It's not available in the settings or settings>phone);whereas,it's showing on my phone.
So what do you guys recommend him ? should he try a fresh OS install ?
androiphone is correct, but if it's not showing in Settings, then something may have hiccuped as it should be there. Check if it's available on a contact. Otherwise try a fresh reinstall.
As Carl G35c mentions, first try a restore and load the backup -- if it's still not showing up in Settings, then you may need to do a Restore and set up as a new phone.
