Also will your custom firmware ask for activation or I will be hacktivated as default?
Actually I heard that I can fix battery problem by activating my iphone with the oficcial sim (I have one), I want to try that and I was looking for a solution to restore my already “hacked” iphone 3G with 4.2.1 ios and 6.15.00 baseband because I need it to be NON-ACTIVATED nor hacktivated but ultrasn0w automatically makes it hacktivated.

I’m on 3.1.3 ios and 6.15.00 baseband right now!!! Your video is great. Thank you much.
I want you to upgrade your video a bit because it might not be understandable to some newbies (i’m not registered on youtube so i write it here):1) Description says “How to downgrade iPhone 3G iOS 4.1.2 to 3.1.3 without SHSH and BATT ISSUE FIX”
i think you misstyped with 4.1.2. Change it to 4.2.1. It might confuse some people.2) Step 6 says “unplug usd cable from your computer not phone” I think you should add to step 6 “then plug it to computer again”
3) Between step 2 and step 3 I think there should be step 2.5 that says “after you started iREB process iTunes will open automatically you need to close it till the iREB finishes its work”
Regards!!

I have a 3G with 4.1 and baseband 6.15. Should I upgrade to 4.2.1 official firmware before applying this custom firmware?
I haven’t tried, but I have a feeling the official Apple firmware won’t work on my phone due to the baseband conflict.
Any tips for me? Thanks
