    "During the following process the memory of your iPhone will be reorganized. This will have a positive effect on the quality of the GPS reception. The internal memory will be deleted completely during this reorganization. Therefore it is necessary to make a backup of the software (as described in step 1).

    1. Please connect your iPhone to iTunes and synchronize it. Afterwards
    please rightclick on the iPhone icon (in the left menu bar of iTunes)
    and choose "backup". iTunes will now create an complete backup of
    your iPhone content and settings.

    2. Disconnect your iPhone from the computer and connect it to the power

    3. On your iPhone choose "Settings" -> "General" -> "Reset".

    4. Choose "Erase all Content and Settings" and confirm the deletion.

    5. The following erasing procedure can take up to two hours and more,
    depending on the model and storage capacity of your iPhone .

    6. After the procedure has finished, please connect the iPhone to your
    computer again.

    7. Now restore your content and settings to your iPhone using the previously
    created backup.

    In addition, a limited GPS reception can have the following reasons:

    Poor positioning of the iPhone in the car. Like every portable navigation
    device, the iPhone should always have a "free view" to the sky. Metallized
    windshield. Usage of design covers or protective covers. While using our
    NAVIGON software, please avoid using such covers as they can severely
    impair the reception of a GPS signal.

    Will going through this process mess up my Jailbreak?? In other words, can you do this on a Jailbroke phone?

    Nor Cal, USA
    Erase all Content and Settings will remove the jailbreak.

    What/who is instructing you to do this?

    It's a navigation app(Navigon), that I'm having intermittent GPS problems with.

    You never do this on a JB phone. You kill the JB and screw up your phone; you have to DFU to get it back.
    Always use restore in itunes if you need to erase your phone.
    Any kind of erasure will wipe your jb.
