(adsbygoogle = window.adsbygoogle || []).push({}); Okay. First of all im typing this on my ipod so sorry for any speelling mistakes.
A while ago i intended to jailbrrak but was already on 3.5 and when i found out there was a downgrade i was on 3.55.
I saw some topics on custom firmware and i need some help understanding whats happening.
Im on 3.55 unjailbroken (obv) and if i got a custom firmware could i use it to downgrAde or does it install a explooted version of 3,55.
If i downgraded i could jailbreak correct?
If it created a. Explooted version i could use a jailbreak. Right?

Help will obviousley be very helpfull. Thanks
