Hi, I have have purchased a new iPod Touch 3G. I want to jailbreak it. But i have some doubts. please help.... 1.) I have read a tutorial for jailbreaking 8gb iPod Touch, using blackra1n here - http://www.ifans.com/forums/showthread.php?t=259842&highlight=jailbreak ipod touch. Will it work with my iPod too ?? 2.) If I jailbreak, will i be able to sync using iTunes & install apps from apple store ?? 3.) How can I backup my iPod Touch before jailbreaking ?? Is it simply right clicking the device name in left pane of iTunes & select 'Back Up'. 4.) Since iTunes backup the iPod before every sync, won't it replace my backup made before jailbreaking with the latest one. Then how will i be able to restore my iPod to make it un-jailbreaked( in case I need it ) ?? Please Help.... THANKS !!!!
