A friend created CutePress [1], a GPLv3 mobile app that is a client to WordPress. Some guy ported that app to BlackBerry [2] as part of some competition but the person did not give attribution to my friend's project, though at least a link to the ported source code was provided.<p>My question is, if an app is GPLv3, can anyone get away without pointing to the source code, providing patches or link to their fork, the original project's website, author info. Further can anyone distribute under the same name and use icons/images which may not be necessarily under GPLv3?<p>[1] http://code.google.com/p/cutepress<p>[2] https://appworld.blackberry.com/webstore/content/20079187/?lang=en
