    Default Old iPhone 3G: any point in upgrading to 3.1.2?

    Hi all!

    My apologies if this matter has already been answered, but I have failed to find the answers to my questions by browsing and searching the forum. I've read many a post regarding people's wish to upgrade to 3.1.2, but nary peep about why.

    I have no desire to fix what is working. The official Apple promo page on OS 3.1 ( Apple - iPhone - New features in the iPhone 3.1 Software Update. ) does not appeal to me. I use the iPhone as a data only Internet device, browsing and using a few apps. I don't use iTunes and I don't care about the phone features. I'm only interested in upgrading if there are some real functional advantages from the upgrade.

    The underlying reason for me asking is that I have finally decided to unlock my device. A lot of the unlock tools either require or recommend 3.1.2, but I understand that the unlock can also be performed without upgrading. For obvious reasons I do not want to attempt any upgrade which would risk a baseband upgrade.

    If 3.1.2 is required to unlock the device, then that is a sufficient reason to upgrade. If this is purely optional, then I would like to know what other tangible reasons there are for upgrading.

    I understand that some apps require 3.1.2 to work. Is there a list of 3.1.x apps or some other way to find out which they are without manually browsing the apps in the app store? If they are only games then I don't care.

    Does the 3.1.2 upgrade in any verifiable way inprove battery life or reception? These would be sufficient reasons to upgrade.

    Any other reason to upgrade?

    Regarding the matter of unlocking, the tutorials on iClarified recommend backing up the firmware before jailbreaking the phone, yet using a different firmware to restore the phone before starting the jailbreak.

    I have no local data of importance on my phone. Is the backup of the current firmware necessary, ie. to have a known good firmware if the jailbreak fails? Can't the phone always be restored to factory condition using available online or iTunes firmwares?

    Is the point of restoring a different firmware to the phone, that the jailbreak requires the exact same firmware version on the phone as on the jailbreak app to work? This would obviously be a problem if a jailbreak was attempted on the current firmware if it had not been backed up previously for the jailbreak app.

    Is RedSn0w the currently recommended jailbreak apps? Host options are Windows XP and Ubuntu. The Mac option is not applicable.

    Thanks in advance for any views on the upgrade matter.

    I would definitely not recommend blackra1n. Experience has shown that it has a lot more post-jailbreak problems than the dev-team's jailbreak programs. What you gain in speed, you pay for later when the device crashes and you can't recover.

    Pwnagetool is the tool I would always recommend to users as a first choice - it preserves baseband (which is a good habit to get into if you ever want to use unlock).

    If you are on windows (and thus can't use pwnagetool) or you want a quick jailbreak (and you are aware that your baseband will be upgraded) then load OS 3.1.2 and use redsn0w.

    Don't use blackra1n - and if you MUST use blacksn0w for unlock use RC2 http://www.hackint0sh.org/f230/117709.htm
