Anybody knows more about the bb downgrade signatures? Or how to backup them like the shsh certs? Or how to use the replay attack here? Actually this is more related to baseband firmware (missing wiki article?) and not to this iPhone 4 hardware. |

Revision as of 18:18, 16 July 2010
Device for iPhone 4
Are we sure this is the baseband?
The infineon spec-sheet says "HSDPA/HSUPA capabilities of 7.2Mbps/2.9Mbps".
At the keynote Steve mentioned 5.8Mbps HSUPA. Iemit737 19:26, 21 June 2010 (UTC)
Running "string" on the new baseband files shows "XGold 618" multiple times. --Miketress 19:35, 21 June 2010 (UTC)
Ok, awesome. Thanks for finding this so quickly! Iemit737 19:50, 21 June 2010 (UTC)
Very unlikely it's the 618 after looking at the spec sheet. In case anyone is interested, | X-Gold 616 spec sheet, | X-Gold 618 spec sheet. D235j 21:43, 22 June 2010 (UTC)
Actually, it's the XMM 6180. ebl.fls says so. --oranav 21:56, 22 June 2010 (UTC)

The baseband is signed with an at+nonce which is a random string generated on every bootup. Therefor, it is not possible to cache the SHSH signatures with a replay attack.
