3gs fw3.1 jailbroken via blakra1n => ios 4.0.1
I'm a bit confused. I have a 3gs running version 3.1 that I used blackra1n to jailbreak. I have SHSH's for 3.1, 3.1.2, 3.1.3, 4.0, 4.0.1.
I would like to get 4.0.1 and used jailbreakme.com. However, I am confused as to whether or not jailbreakme.com is my best option.
1. I have read posts that say to do a restore in iTunes before updating instead of just updating to 4.0.1 but will that erase cydia and in turn erase my SHSH's?
2. Is there a better option for updating to a jailbroken 4.0.1?
I'm a PC user if that makes any difference.
