The iPhone 3GS has received two major updates in the last 24 hours to software unlocks, purplesn0w RC2, and ultrasn0w.09 reports theiphoneblog.

The fresh version of purplesn0w RC2 features fixes for 3G issues, patches CommCenter, leaves no trace of the baseband after it runs, and is much more reliable and clean.

The iPhone Dev Team’s ultrasn0w.09 features, works with both iPhone 3G and iPhone 3GS, does not patch any mach-o binary at all, no popups about “missing SIM”, no network issues and no race conditions, and is almost 7000 times smaller that its nearest rival.
