There is a bug when adding or Editing a Custom Phone Label. I use my iPhone 5 for business and use this function a lot. Many of my contacts are companies and have numerous numbers and I have to label them such as Reception or Accounts or even first names. I created maybe 100 Custom Labels and use many Labels again and again. After updating to iOS7 the list of Labels are now not in alphabetical order. This means I have to scroll through the list again and again. What a pain. Is there a way around this. Otherwise I hope apple sort this out soon.
