iCloud delete and remove device and photos Inexplicably I wasn't able to enter my 4 digit password on my iPhone anymore. I tried so many times that my iPhone was deactivated.
I powered off my iPhone and restarted it, but no chance.
Afterwards I asked to delete my iPhone from iCloud.com, but first I requested to erase the phone.
What happens to my iPhone if I've erase my iPhone via iCloud ("Find my Phone") and afterwards I also delete my iPhone from my iCloud account?. Does the request to delete my iPhone still apply?
Yes, the iPhone will still be erased - when you start your iPhone you'll be asked to set it up again as a new one.
EDIT:
It also described on Apple's Support page: https://support.apple.com/en-us/HT204306

Erase using Find my iPhone
If you enabled Find My iPhone through iCloud, you can use it to erase your device.

Go to icloud.com/find.
If prompted, sign in with your Apple ID.
Click All Devices at the top of your browser window.
Select the device you want to erase.
Click Erase [device] to erase your device and its passcode.
Now you can either restore from a backup or set up as new.
