ultrasn0w 0.9 is a iPhone 3G unlock tool developed by iPhone dev team for OS 3.0 firmware. Most of the issues and bugs have been fixed in ultrasn0w 0.9 version that were reported in previous version of Ultrasn0w. iPhone dev team also claims that ultrasn0w 0.9 is far better as compared to purplesn0w to unlock iPhone 3GS 3.0 firmware. According to iPhone dev team-
“ultrasn0w uses 152 bytes of properly malloc’d baseband RAM, which is 0.015% of what purplesn0w uses. Put another way, purplesn0w uses 6900 times more RAM than ultrasn0w (and doesn’t let the O/S know that it’s using it, so the O/S still thinks it’s free to use. When it does use it, the baseband will crash).”
