I have an iPhone 3GS currently running iOS 4.0.1 that was previously jailbroken. I would like to upgrade it to a better version of iOS and need detailed information on how to perform the upgrade safely.

The latest and best version of iOS for the iPhone 3GS is iOS 6.1.6. To upgrade, connect your device to your computer and use iTunes to perform a restore to the latest available firmware. If you rely on a carrier unlock, you should use a tool like Redsn0w to create a custom firmware to preserve your baseband before updating. If you do not need an unlock, a standard restore through iTunes is the simplest method. Once you have updated to iOS 6.1.6, you can jailbreak the device using the p0sixspwn tool. Detailed step by step guides for these procedures can be found in the iClarified tutorials section.
