Hi xiebin and Benny, I have been asked to contact you regarding the Busybox software that ZTE include in their Blade software for both Android 2.1 and Android 2.2. Busy box is licensed under the GPL (http://www.busybox.net/license.html) and as such any organization using it are required to distribute the source code that was used to compile the version released with their phones. The person who has contacted me wants to fix some bugs in busybox which are causing him issues. Please review the license obligations for busybox as listed in the link above and arrange for the source code for this software to be made available. Regards Rob
