Many of iPhone user asking on how to delete contact all simultaneously.
Either by trick, by apps, by cydia or through iTunes.
Below are the methods that commonly used by iphone user to delete all their contact:
» Click to show Spoiler - click again to hide... «
1. Delete one by one.
This is simply using Contact > Edit > Delete Contact.
This is much more frustrating because of time consuming.
2. Reset all contents and settings.
This is kinda worried for novice user since they don’t know how to recover their settings to original.
And its much more worse if their phone is locked set.
3. Through cydia apps.
Cydia apps such as SimManager, Erase Contact, Delete Contact and else.
But this method requires the iphone jailbroken.
4. Reset through iTunes.
Remove sync from iTunes > iDevice > Info tab > untick sync contacts > add empty list from Outlook or google > let it sync again = empty.
But this method require the iphone to be connected to the pc/laptop/macbook.
What if the user is out at shopping complex or maybe at neighbour’s house?
Kinda troublesome to do that.
Hence, I would share another method to delete all contact in iPhone that:-- require
NO internet connection [no need to use wifi or cellular data.]
- using
NO iTunes [which means no need to connect to pc.]
- using
NO any additional apps [which means no paid apps.]
-
NO Cydia! [Which means it is applicable to non-jailbreak iphone.]
- can be
done within 5 minutes! [which means u free lots of your time]
