hey congrats

flash the device to pr1.3 use the international ver
install backup menu start the device with the keyboard open you can perform backups, boot to terminal, usb host mode.
cssu will give you the latest in community enhancements
enhanced busy box and bash
power kernel v49 is the latest kerenel for the device

it is very similar to debian distro ..you can find the maemo sdk in the tab above marked development. wikis are kept up to date use the power search on the right in liu of the forum search. debian ldxe is not installed by default ..it has been compiled to run via chroot on the device. Baktrax distro has also been compiled to run on device if that interests you oh and windows 3.1 lol

good luck and have fun

edit: faster app manger is good for installing programs, not for pr updates or cssu and you can also use apt from the command line if you prefer you will also need rootsh to get root access

edit2 also you may have to add extra testing and devel repositories for some of the above apps
