    From what I've read around you cannot uninstall a system bar once installed.. Maybe would have been possible if there was root.. Guess you will need to do a wipe though you wait for opinion of a few more people who might have tried it ..

    A system wipe would be best but there my be another way............ Have you ever heard of side loading within Google Chrome????? There is an app that runs in chrome called "Playbook App Manager", it works very well and connects through usb as well as Wifi. With this app you can remove system apps. I have done it but............experiment with it at your own risk.

    If they were signed apps, you cannot. Find your source again and reinstall from there.

    Chrome won't allow uninstalling of system apps.

    There is a way to remove system apps: You need to get a hold of the BAR file (you should already have this seeing as you installed it in the first place), extract it, remove the signature (involves deleteing stuff from the MANIFEST.MF file I believe), edit the manifest to allow deleting, sign it with a debug token, install that debug token on your PB, install the edited app, then delete the app. xscaha mentioned this one time, I've never actually done it. I may try again sometime (I only tried very briefly before).

    Generally, you need to be able to get the actual Native app and pull it out of an archive or backup. Inside the bar file (really a zipped series of files) will be a file that contains "coding" info. Basically, you remove the coding that Rim added to the file, replace it with YOUR own version that allows Deleting and then you need a way to "officially stamp" the file (signing), repackage it and put it on your pb. That newer version will presumably overwrite the official version. Now you can Delete it.

    I'm sure that there are better explanations of this process - if it even works!

    That clarifies a little, any tutorial vids on YouTube that anyone knows about?

    I'm afraid I've never even done it myself, I have just read that it can be done (xsacha posted about it in these forums before, he's pretty knowledgeable about this stuff so I'd say it's correct).

    There is an easy way for this, at least on a BB10 phone. Extract a bar you need to remove from a firmware. Sideload it and let it overwrite previously installed system app, voila, you can now remove it with help of Chrome extension (maybe even using the device itself, didn't checked).
    But there is no much point in doing this, as it will be reinstalled at the next (major?) OS update.

    Does this work for BB10 too? This thread: Repakaging bar files? shows that it's impossible to deploy an own package using a name of a system app.
