How to add contacts to iCloud from iPhone?

My iCloud account is syncing fine with everything that is new to my iPhone 5; when I add a new contact, it syncs to iCloud with no problem. The problem that I'm having is that I have maybe 100 un-synced contacts on my iPhone 5. This occurred because the contacts existed on my iPhone before I ever had an iCloud account. Every contact after the creaton of my icloud account has no trouble. But my qyestion is, how do I transfer those pre-existing contacts into iCloud?

I have tried, without success:
- turning contacts off, and then back on and merging them.
-manually dragging contacts into the icloud/contacts page
-deleting icloud from phone and re-installing it
-unchecking and checking the contacts box inthe icloud taskbar on my computer
-uninstalling and reinstalling the icloud taskbar

basically everything short of completely deleting my apple account, creating a new one and starting over, which I'm not open to doing because I would lose a lot of saved data.

Really need some help on this

You can use iPhone Manager. It is compatible with all Apple devices.

  • Why did the iPhone update add back a contact/contacts I had deleted? Pretty irritating to see a person show up in my contacts whom I deleted over 6 months ago. A name and face I don't want to see. I mean I deleted the pictures and everything yet I just found that his pic and all his contact info was in there. Is it just a glitch where it did a restore from 7 months ago for some odd reason!
  • 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?
