Hello, I have an iPhone 3G with firmware 2.01 on the Rogers network in Canada. I want to jailbreak with Winpwn 2.5 (which also has quickpwn). Should I upgrade my firmware to 2.02 then jailbreak it or should I keep 2.01? Is there a difference? Also, which would be best to use - winpwn 2.5 or quickpwn? Thanks.
