    Storm can function in autonomous mode already. Verizon 8x30 series devices require PDE cooperation from the provider. The engineering screen settings won't change that. There is a PDE settings page, but it is not possible to set application ID or application password globally in that (as the field does not accept semicolons, used to delimit that info).

    The most promising avenue is specifying PDE credentials on a per application basis in source code. I've published the VZNav PDE credentials, but applying them to other applications isn't quite as straightforward as I would have like (and in any case, requires the application source code, and a RIM signing key).

    Thyth,

    A question. I have seen discussion of using the Qualcom Product Support Tool to correct GPS issues with the Storm. Are you familiar with this and do you have any comments?

    Thumbs up

    Thanks for the info, by the way your code generator page is awesome. I figured there had to be alot more to the gps then a option to disable all restrictions. well thanks for shutting down my hopes and dreams

    I'm not familiar with it. All of this GPS stuff is just curiosity for me though. I don't own any locked down device. It just happened to be a nice deliverable result to my BlackBerry reverse engineering efforts.

    I do know that there are guides out there to correct GPS issues using 3rd party utilities that set PDE parameters on a device at a fairly low level. It's my understanding that you can set the same parameter using the engineering screen. However, if those 3rd party utilities work on a lower level than the engineering screen (which itself is lower than the JVM), it might be possible to set PDE parameters that include an authorized application ID and password (such as VZNav's).

    PDE is wholly a CDMA abomination though for A-GPS, and again, I don't own any such devices. Any sort of progress in this arena is significantly slower as a result.

    I don't know yet whether this sort of unlock is possible, even after I reverse engineered the location based service provider API in the operating system. Providing valid PDE credentials seems more viable than trying to hack autonomous mode into the firmware (as there are digital signatures to verify everything), especially since I lack the level low level systems engineering expertise that's common on say the iPhone Dev Team.

    I did find two major classes of security vulnerabilities in the BlackBerry operating system during my analysis, though, which could be used to gain a significantly higher level of control over our devices. One might be usable to bypass any code signature requirement on the devices, up to and including directed invocation of operating system internal routines (albeit, in a highly version and device specific manner), which normally requires signing by RIM's '3' signature. The other might be usable to break out of the JVM, and into the native operating system environment (which is completely unexplored territory, as far as I know).

    But, to be honest, turning either vulnerability into an exploit holds little interest for me. Development for this platform is severely held back by the outdated operating system, closed nature of the system, and the unfriendly API offered to developers (look at the pitiful state of web browsers, for one). I know a lot of people think this platform is the most secure mobile device platform (especially given the current track record), but from what I'm beginning to see, that's largely just because of the giant mud-ball of obscurity. Once you have a functional module (i.e. COD) decompiler, and you begin to learn how the OS works, it all starts to break down. So, I'm jumping ship to Android, where I can verify the security of my device down to the core, right after I release my final BlackBerry application.

    help unlocking gps

    i went digging through the device.xml file the other day and i found that all 8330 were missing a code in the source that other have but not the 83xx series, the like that is missing is GPS="true" could i think this is why the curve's do not have gps the 3rd party applications more than likely do not have this command in them but bb maps and vz navigator do, how do i upload a modified version of this source to my 8330 to test and see if my gps will become enabled?
