firmware 3.0.1

The latest firmware update released by Apple may have improved security and added features, but some iPhone owners are having problems. Reports from users on the Apple support forums indicate a major problem with updating to iPhone OS 3.1 on the iPhone 3G.

Users are ending up with bricked phones, and iPhones that crash several times, requiring a hard reboot. Holding the sleep and home button doesn't always work, however. Some users are finding it necessary to downgrade to iTunes 8 and firmware 3.0.1 to solve the problems.

Apple released the iPhone OS 3.0.1 firmware update the other day to fix an SMS security flaw. This has rendered purplera1n useless, and creator Geohot has abandoned the project for now. That being said, redsn0w from the iPhone Dev-Team still works.

There's one thing to look out for when using redsn0w to jailbreak 3.0.1. After updating to the official 3.0.1 through iTunes, running redsn0w will ask for the IPSW file to use for jailbreaking. Select the 3.0 IPSW, not the 3.0.1 version you just installed. For owners of the iPhone 3GS or a newer 3G, you may not already have this file.
