I've had an itouch for less than a year. it's jailbroken on 4.1 firmware with limera1n. and i can't open the mail app on it because it opens and exits, my internet doesn't work, and tap zoo can't connect but it shows the wi-fi icon is at full strength. so the wi-fi works but it can't connect to the internet and we've already restarted our router once so do i need to restart it again? and in 2 hours 1/3 of it's battery went away after it was fully charged even though i didn't use it. plus, music makes the battery go away like when a video or app is being played. how can i make the battery stop draining constantly? and how can i get the internet on it to work? is the jailbreak the problem? or do i need to restore it and use the warranty?
