Today Dean K has released to us a new handy PKG tool that makes it easy for users to install .pkgs and write through FTP access. Check out the his quote and the download link below.
Quote (Dean K):
This is a small handy tool for installing PKG files via the "bubble"/PSN method. It may be handy for Rogero 4.30CFW ver. 2.00 users. Rogero is preparing a firmware version which will have it 'build-in' in /dev_flash so you won't need multiMAN and you can't break/delete it, since it will appear in [/app_home] when you boot the PS3 and will come preinstalled.
It comes with background running FTP server and /dev_blind mounted (for write access to /dev_flash).
