    I have a jailbroken 3G iPhone, on 3.1.3. I did it some time ago and am in two minds what to do now...

    I want to install the bookmark app, (which requires ios 4.0 or over), so I decided maybe I should un-jailbreak and update to the latest ios.

    1. Do I simply run the update in iTunes and that gets it back to stock? Also what is the view on 4.2.1 on the 3G? Are there still performance issues or is it safe to upgrade?

    Ever since I got the iPad I have never used the data on the phone, so I changed my PAYGO account to a daily plan. To make sure the data network is turned off, (and Im not charged for that day), I use that control panel thingy that allows you to turn 3g, wifi, data, etc, on and off without going into settings.

    2. I understand that ios 4.2.1 allows you to turn off cellular data from the settings, would this be adequate to completely shut down the data on the phone?, (so I dont get charged).

    Is there anything else to consider?

    TBH I rarely use the iPhone, it was mainly used for internet and games - which I imagine is the same for a lot of people - now I'm using it as a phone, (rarely), and an mp3 player......and I don't need to pay for both my iPad and iPhone to be on data when there is no need.

    I would like to get the process clear before I start anything, so I don't screw anything up, so your help will be appreciated.

    Thanks

    The iphone 3G is very slow on anything 4.0 and higher. Up to you if you want to try it but to me its unbearable.
    To restore or update to stock 4.2.1 all you gotta do is plug it to itunes and click update.
    It will go up to a stock 4.2.1
    And yes all you gotta do is go in to settings and turn off carrier data.
    That will block everything but wifi internet use.
    Good luck.

    if you don't want to preserve your phone baseband 05.12 (which can be unlocked by ultrasn0w), then follow AJ's instruction to upgrade it to stock 4.2.1. However, if you want to preserve this baseband for future unlock, then create a customs firmware with Pnage tool or sn0wbreeze and restore your phone to it.

    Hmmm, thanks......I'm still in that wary to do anything mode, so I think I'm gonna leave it alone. The drawbacks seem to be outweighing the benefits.

    I should really buy a 4s and get over it, but I decided I would wait to see what the 5 brings, (and I'm sticking to it.....probably). ;)

    Its a shame, but I can't have everything. Thanks again.
