Ok, so you have an ipad 2 with a fake smart cover that doesnt turn it on and off, and your old snap on back cover wont quite fit. Here's the solution. (This is just what I did. Dont come blaming me if you mess it up.) 1. Smart cover. The new ipad is triggered (on and off) by a single magnet. This magnet HAS to be the correct polarity to work. If it doesnt work on the ipad 3 but it does on the ipad 2, all you need to do it cut is out carefully (think exacto) from the inside of the cover, flip it, and put it back in. (Location of on off magnet here: http://cultofmac.cultofmaccom.netdna-cdn.com/wp-content/uploads/2011/03/smart-cover-magnets.jpg ) If you are careful and cut us with a sharp knife, you can use a tiny touch of hot glue and the incision will almost dissapear. Careful using glue that could scratch the screen. 2. Back cover. My casecrown snap on smart cover compatible back cover didnt quite fit the ipad 3, but it was close. SO, I turned on my oven (yep oven) and set it to 170F (the lowest setting on the oven). I put the back cover (NOT THE IPAD) in the oven on a towl (important) and checked it every 2-3 minutes until it was hot. When quite hot, but not melting, take it out and snap it on the ipad. The cold aluminum will cool it almost immediately, and it will be reshaped to the new size. Works perfect! This was my cheapo way to get back to the perfect case combo for the $$. I have like $6 in the back cover and $12 in the smart cover. Now they both work perfect on the new ipad.
