Wow, looks like Badflash got a bunch of I-openers for anyone still interested in one of the neatest little systems out there. Here's a cut and paste:
IOPENER Version V5 - $49.99 + $15 ship
These are un-modified AT&T refirbs in perfect working order and ready to hack. No glue, cut pins, etc. Includes keyboard and power supply.
For orders outside the USA we will confirm any additional shipping charges (in excess of the $15) prior to sending out the unit.
These units require a Bios upgrade chip to support a hard disk.
