Revisions

3.9

This is the old bootloader from the iPhone/S-Gold 2. It is vulnerable to Minus 0x400 and IPSF

4.6

This is the new bootloader from the iPhone/S-Gold 2. It is vulnerable to Minus 0x20000 with Back Extend Erase

5.8

This is the bootloader from the iPhone 3G/X-Gold 608. It is, in contrast to 3.9 and 4.6, sig checked on startup. There is an exploit where the main fw cert is passed with the loader instead of the loader cert, and it checks the main firmware instead, allowing you to upload unsigned loader code. This has been fixed in 5.9. You can downgrade from 02.30.03 to 02.28.00 using pHaseBanDowngrader (by pH) in the Bootloader 5.8.

5.9

This is the bootloader of version 2.1 and 2.2 OTB (and some 2.0 OTB) iPhone 3G/X-Gold 608. Still has no known exploits and it was released as soon as Apple knew iPhone Dev Team could downgrade their iPhone 3G baseband from 1.48 to 1.45. Now, all the iPhone 3G has bootloader 5.9 and higher.

6.2

This is the latest bootloader of version 2.2.1 OTB in 2008 iPhone 3G/X-Gold 608. Still has no known exploits and it was released as soon as Apple knew iPhone Dev Team could unlock their iPhone 3G baseband version 2.28 by yellowsn0w. Now, all the iPhone 3G 2.2.1 OTB has bootloader 6.2.

6.4

This is the latest bootloader of version 2.2.1 OTB in 2009 iPhone 3G/X-Gold 608. Still has no known exploits and it was released as soon as Apple released firmware 3.x beta for testing. iPhone 3GS and iPad 3G+WiFi units contain this bootloader as well. As of the 3.x firmwares (baseband v. 4.x), the baseband now contains the loader of bootloader 6.4.
