Hi. I installed iOS 7 on my iPad 3 yesterday and haven't found much wrong with it except for one really irritating problem that I can't find a solution for anywhere. When receiving an iMessage the contacts name is displayed in the notification centre and on a banner but in the app itself it only displays the contacts telephone number... This makes it really hard to know who I'm talking to! I've tried signing out and back into iCloud, re-syncing contacts, etc. Everything online is just a solution for the "short name" in Messages problem but there is literally nothing for it just showing the number. Please help, I'm pulling my hair out trying to fix this!!
