I have iphone 3gs with new bootroom running on 3.1.2 jailbroken with blackra1n.

When i tried to restore my phone in itunes, i got an error which said that the device is eligible for the requested build.

How can i safely upgrade to ios 4.

Can i just press the upgrade button is itunes? will that brick my phone?

thank you all in advance!

just upgrade to 4.0.1 dont be afraid to just hit the button.

Won't brick your phone, nothing to worry about. Do it soon so you can jailbreak 4.0.1 before apple comes out with an update and stops signing 4.0.1 or if you don't want to JB right now back up your shsh blobs with TinyUmbrella (google it) so you can downgrade to 4.0.1 any time in the future.


good luck.

brace yourself for a ton of people telling you that you're stupid for creating a whole new thread about this.
