Off!
Aahh!! I'm in good company! Can't believe I had to resort to Youtube and other sites to resolve this problem. To those of you who said it was easy ... kudos to all of you. HOWEVER!!!!!!! For some of us, after all the instructions the bloody cover still won't come off.
Anyway, I FINALLY got mine off after only about 20 mins. of trying. Here's what I did. I tried the palm thingy and it did not work. I tried the finger thingy and it didn't work. I tried the palm thingy again and it still did not work, then I tried the finger thingy again and it still did not work ....
So in the end, I tried using my thumbs. Right thumb at where the little arrow is and the left thumb at the opposite end of phone. Then I just pushed down on the cover while pushing it towards where the arrow was pointing. Then I decided to push in the opposite direction, this time towards the arrow. I did that several times in a "back and forth" motion and the cover finally "pop" out. I just went "Wow ... it came off!!!"' "Shit!"
Hopefully the above maneuver can help others that can't do the palm or finger thingy. I really hope what I just did will work again for me in future.
