Has anyone successfully hacktivated, jailbroken and unlocked an iPhone 3GS with bootloader 6.4 and BB 5.13.04 with 4.2.1? The other day I spent over 8 hours trying to update my phone creating a custom firmware with PwnageTool (which never worked correctly, either my phone wouldn't go out of DFU mode or I would get stuck on the Apple loading screen), and when it did (once), I wasn't able to hacktivate it. I believe one of my issues is either the PwnageTool 4.2.1 bundle doesn't work with my phone or I haven't found the correct one. I ended up restoring back to 4.0.1 with limera1n. Anyone has any ideas or experiences with a same setup as mine? I'd really like to upgrade but not feeling to go over all the trouble I went the other day. Thanks!
