no network install
If you don't have available network for your 770, do the following: Get http://maemo-hackers.org/apt/pool/ma..._5.5-1_all.deb http://maemo-hackers.org/apt/pool/ma....5-1_armel.deb http://maemo-hackers.org/apt/pool/ma...1-1mh9_all.deb http://maemo-hackers.org/apt/pool/ma...1mh9_armel.deb http://maemo-hackers.org/apt/pool/ma...0-4mh1_all.deb and http://maemo-hackers.org/apt/pool/ma...mh13_armel.deb and place them onto mmc card.
