How to delete multiple contacts from my iPhone?

I have the name and phone number of one contact on my iPhone about 100 times. Is there an easier way of deleting them than doing it one by one.

  • Whatsapp contacts - if they're onnm contacts am I on theirs? I have the phone number of an old friend stored on my iPhone and they also show on my whatsapp contact list… Does this mean that they still have my phone number stored in their phone and also have whatsapp installed on their phone? The chat thing says they haven't been seen since 28th sept? If they didn't have my number on their phone would they still show as one of my contacts on whatsapp?
  • My contacts keep changing into my parent's contacts? I'm using my Dad's old iPhone 4, so it has all of his data. I cleared out everything that was his but I hate the part where each time my parent's add a new contact to their phone, everything syncs over to my contacts, so I'm scrolling down my list and see a new person I don't know but my parents do. Is there a way to change this?

  • Iphone 3GS, how to delete multiple photos? So i have around 1600 pictures on my Iphone 3GS, can i burn these onto a CD or something (if so do i need to buy some special CD or just a blank one)? Also once iv'e managed to move these to somwhere safe i want to delete them all off my phone, 1600 individual pics is going to take forever to delete so how can i do a multiple delete? I know i sound stupid but i know nothing about phones and stuff xD
