I Need some clarification before using Blackr1n
I have the iPhone 3GS 3.1 05.11.07
1) Is there any thing that needs to be backed-up from the iPhone before carrying out the JB?
2) Any other steps that need to be carried out before JB incase something was to go wrong?
3) Regarding the option to install Cydia, Rock & Icy - Is there any reason to not install them all? What are the pros & cons of each?
4) Is there away to go back to virgin iPhone again, that is, to make the iPhone back to exactly what i was before the JB?
5) Anything else I should know?
Thanks in advance for any help provided.
