Just confirmed, if you buy an '002 off the shelf and pair it with a dev
account, it's a developer edition. :)

001 vs. 002:
002 is a solder-down module. It has more I/O than the 001 SD module,
doesn't require the ID chip since it's not going to move from device to
device, and requires that you bring your own phototransistor and LEDs
for status and BlinkUp.
002's are indended for mass production, and mass produced products
require a subscription for the back-end. Having said that, there are
certainly hobby projects using modules, and you can get them in small
quantities from DigiKey and Smartmaker. Smartmaker has breakout boards
for them as well. The "Amber" reference design includes some sample
power supply and opto circuits if you want to go with the 002.

Thanks for that link. I was not far off with my exaggerated conditions -
in the desert on batteries ;-). Unfortunately the BER and antenna type
are not stated, but they were not after a carefully controlled
experiment with that post.
Anyway the achievement that matters is the 100+ meters in a typical
configuration and, considering the intended applications, it's a winner.
Yeah I went around looking for a module before coming across the
002...which would be great for integrating an imp into a product and
more reliable than the sd card connector. I'm trying to get my head
around the differences between 001 and 002. Besides the higher number of
IO pins, they say that a developer's edition is not available for 002
and a subscription requirement is mentioned for 002.

The RF design is exceptionally good. (I've known Hugo for many
years, he
knows his stuff.)
Here's the range test, where they lost connectivity at 790m. I know
that
the AP they used was a Cradlepoint MBR1400, and while this was an
IMP-002 (the solder-down module), the RF section and antenna are the
same.
