iphone 4 ios5.0.1 did a jailbreak long ago when it was available. everything went fine until yesterday. the phone got stuck on normal useage and i had to reboot. it never got past the apple logo so i did a dfu restore and redownloaded the latest redsnow jailbreak to rejailbreak. now the phone will get stuck when the phone gets rebooted and wont get past the logo. its happened 3x now. why is this happening? i went for over a month w/o nothing and then all sudden this happens **update** i believe what is giving me a problem is netatalk.. sometimes it requires to restart the phone for the iphone to show in finder. but the problem is ive had netalk work before and why is it doing it now?
