Hi, I got iphone4 as a gift but i accidentally update to ios via itune now my baseband become 04.11.08 so i can't unlock. what firmware that apple still signing that i can downgrade to. I learn that basebase 04.10.01 is unlockable. How can i downgrade to baseband 04.10.01
thanks

I believe Apple has stopped signing 4.3.5 now so it is impossible for you to downgrade your baseband.

You can still try to restore to 4.3.5 is you want but you will most likely get a 3194 or device ineligible error.

I can comfirm apple is only signing 5.0 firmware, so no more downgrade of bb.

[Simon]

Yup, just tried it myself. No more 4.3.5.

Well that's no more fun. So once ya go 5.0 can't go back

[Simon]

You can go back if you have previous SHSH. Can't downgrade your baseband no matter what now though.

If apple comes out with 5.1 and you want to restore to 5.0 which apple no longer signs, you can't anymore

thank guys, it seem like my phone is not useable. dame it, i still have 1 more year contract with t-mobile. Hopefully, the tool to unlock for baseband 04.11.08 is coming soon so I can start to use my iphone.

Hate to say it but I doubt there will be another unlock at this point.

You could always sell it and get an unlocked/ unlockable one.

so any new devices bought, from now on won't be downgradeable?
that's kinda scary

It's a gift phone so I can't sell it. I will give this phone to my girlfriend since she has AT&T
