Accidentally blocked someone on your Samsung Corby II? Here's how to UNBLOCK that contact!
1. Go to Messages.
2. Press the Pull-up options (between Compose and Back buttons).
3. Go to Settings.
4. Go to General Settings.
5. Go to Block messages.
6. Press the Pull-up options (between Create and Back).
7. Mark the contact(s) you wish to unblock and press Delete.
There! That was easy! Now you should receive any future messages from that number. But I doubt the missed messages will come. You should tell that person immediately what happened :)
Don't worry guys, PostBeard is here to help! Glad to help you, guys! :D
