hi, i own an ipad 3 and my only concern with this ipad is that it can't play 1080p MKV files smoothly. i can play mkv files using avplayer HD , jailbroken of course. since the new ipad 4 is not jailbreakable yet, im wondering will it have the power to play 1080p mkv smoothly ? everything about ipad 3 is enough for me, as i dont do gaming, i only use my ipad for web browsing, watching movies, and reading book and megazines. i'm thinking to upgrade mine to ipad 4 if it can play 1080p mkv smoothly but if it still can't play it, i have no reason to upgrade. 720p on ipad 3 is working fine, but i love 1080p more , since the ipad's screen are able to shows the differences. please help me to decide, thank you.
