[AC Question]

I accidentally imported the contact list details from my business address book using Kies for the first time (about 2000 of them, mostly email addresses) into my personal phone, a Samsung S4. I don't want them in this phone, can I delete them all and just leave all the contacts with a phone number attached? Failing that, how do I delete all my contacts in one hit and start again (wouldn't take nearly as long to re-enter the ones with a number than doing it one at a time)?

Any suggestions to solve this much appreciated!
