Just some JB questions i need answered
1.For example, i wanted to JB my 3.1.3 official firmware iphone to 3.1.3 JB via Redsn0w. I know it will work, but will it also work if I was on a lower firmware say 3.1.2 and below?
2.So from what I understand, once you upgrade your Iphone to 3.1.3 theres no going back, and once you upgrade to iOS 4.0, theres also no going back and this is because for those 2 updates/upgrades the baseband was also updated and prevents any downgrades am i right?
3.Since Ipod Touches dont have basebands i can always downgrade an ipod touch iOS 4.0 all the way BACK to 2.2.1 via DF mode + 2.2.1 recovery file with no problems right?
4.My Iphone is 3.1.3 JB, but i want to update to iOS, what is the most compatible iOS 4 right now for an Iphone 3g? Is there even one or are they all slow?
