No it is safe, I have it and it actually makes my PC faster
Blackra1n is available at the official website (in the related links section)
"blackra1n is a program that jailbreaks versions 3.1, 3.1.1 and 3.1.2 " So if you have any of the listed iOS firmwares then blackra1n will work for you.
no you can't, but if you have a mac you may use Pwnage Tool 3.1.5 (new version), if you have windows you will have to wait
no not with blackra1n
Blackra1n its self is not harmful to you PC as long as you get the programme from the proper place, as you should do with all software. The only time I have heard of blackra1n harming a PC is when it was downloaded from an unofficial website. Blackra1n itself is FREE from official website, although they greatly appreciate donations, and can only function like they do because of this. It is always tempting to download from the first place google shows you, but dont, it just ain't worth it, as so called safe site to download from are not all they are cracked up to be. hope3 I didnt go on and on too much,,,,, happy jailbreaking !!!!
yes
After installing blackra1n it will say that because it accomplishes the jailbreak on the fly which means it patches up the firmware in recovery mode. if you have ipod touch 3g then you have to run it twice (blackra1n). the ipod touch 3g is a tethered jailbreak by the way which means that when you turn it off or to reboot it you have to run blackra1n to get to restart.
Yes, when you finish installing it, it has a bar on the bottom that says, "Uninstall Blackra1n". Just click that and your iTouch/Phone is completely restored.
