Q: apple id cannot active the phone for iphone 4

Hey jehe,

Thanks for the question. Is there a possibility that your iPhone was activated with a different Apple ID? Remember that Activation Lock utilizes the iCloud account. If you continue to have issues, see these articles:

If you recently changed your Apple ID and did not update your Apple ID on your device:

 

1. Tap Skip This Step to continue.

2. After completing iOS 7 setup, go to Settings > iCloud.

3. Scroll down and tap Delete Account, then enter your previous Apple ID and password.

4. If your Apple ID or password are not accepted, follow the steps in iOS 7: If you're asked for your previous Apple ID when signing out of iCloud.

3. Change your Apple ID temporarily

If signing out and back in to iMessage or FaceTime didn't work, try these steps:

 

1. Change your Apple ID to the Apple ID you used previously. You shouldn't need to verify the email address.

2. Tap Settings > iCloud and try to sign out.

3. Change your Apple ID to the new email address that you want to use. You'll need to verify the email address.

4. Tap Settings > iCloud and sign in with the new Apple ID.
