I have never jail broke my device before and am ready to possibly jail break right now i know it would be tethered because for ios 5 thats all there is right now but i was wondering when I jail break it I can not do updates on my iphone correct and then what about like every time my phone backs up do i need to turn off the back up if i do this, i just want some more understanding to what i would have to do and then on top of it what i could not do once i jail break it so that i dont brick my device because i sure cant afford another one because i am not eligible for upgrade till 2013
