    i have an iPhone 3g that is currently jailbroken (using spirit) and unlocked (using ultrasn0w 0.93). I am really interested in upgrading to iOS4, but i cant find a definite "yes" or "no" on whether to do it. I dont want to brick the phone. I dont currently have access to an ATT sim, so if i do this, do i lose the activation? will it even work since i previously used spirit? please help!!!

    First, nobody can tell you whether upgrading to iOS 4 is the right decision for you. You have to weigh the pros and cons. There's no shortcut to making a good decision about jailbreaking.

    Second, it is not possible to brick an iPhone by attempting to jailbreak it. In fact, barring hardware failure, it is impossible to brick an iPhone...period. You can always put your phone in DFU mode and restore to the latest firmware.

    Finally, since you have a 3G, you can just upgrade to 4.0 and jailbreak with redsn0w 0.9.5. You will lose your activation, but redsn0w will "hacktivate" your phone for you. The only problem you might have with a hacktivated phone is with push notifications.

    I'd stick with the 3.0 software myself. If I'm not mistaken (someone correct me if I am) but the internal specs of the iPhone 3G and iPod Touch 2g are relatively close in terms of RAM, processors, etc.

    I upgraded to iOS 4, jailbroke with my favorite apps, and went back to 3.1.2 within a few days; way too laggy (and a huge RAM hog) for my taste.

    There are things you can do to improve that. Use backgrounder to turn off native multitasking for apps you don't need to mulitask, for instance. There's a whole thread on this.

    Other than saying you are running 4.0, there is no reason to upgrade to 4.0 on a 3G. You can do everything that 4.0 does on 3G with jailbroken apps.
