    Can you uninstall SAM once you’re activated? It slows down the boot time of my 3G drastically

  • Austin Ritchie

    Never mind. It turns out that it was a problem with Cydia. A hard reboot fixed everything, and SAM worked well. It might take a couple tries, but it’s worth it

    Can I still use this method even if I’ve already jailbroken and unlocked my iPhone 3gs on iOS 4.2.1 through updating its baseband to 6.15? Or do I have to have it locked to begin with?

    Can I delete SAM and SAMPrefs? My iphone’s battery still drains easily and it even gets hot.

    Question. I already have my iPhone 3gs unlocked. Should I uninstall ultrasnow before I proceed with this method?
