You question doesn't make any sense.
iblacklist is just an app, if you delete iblacklist you just delete an app, of course you contacts will still stay in you iPhone.
If you want to delete a contact, you need to open the individual contact in your iPhone Contacts, select the contact you want to delete and tap Edit and then scroll down to the bottom you will see the Delete Contact button and tap on it. However, this action will only let you delete one contact each time.
If you want to delete all contacts in your iPhone, you need to use iTunes, the steps are as follows:
1. Connect iPhone to computer
2. Open iTunes or iTunes will be opened automatically
3. Select your Device, in this case is your iPhone
4. Next to the Summary page, select Info, you will see "Sync Contacts with"
5. Un-tick "Sync Contacts with", a message will be pop up and ask you to confirm remove contacts, select Remove Contacts
6. Select Apply
After syncing, all your contacts in your iPhone will be removed completely. |
