Finally got an ipad2. I have a magnetic cover that covers the front & back portion of the ipad. When i open the ipad2 & the cover is folded reaching the back the Ipad2 closes or sleeps. I suspect it is the cover - when it reaches the back that causes the Ipad2 to close. When i fold it- with the magnetic cover not reaching the back, no problem. When i activate the Ipad cover unlock also no problem. Is the cover really the cause? Just want to be sure because i still have time to replace it with a new unit if it is a problem. No problem with the ipad at all except that issue. Thanks!
