i'm using an Xbee ZB (back says XB24-z7WIT-004 revE) on a Libelium sheild for an Arduino Duemilanove.
i have two of these set ups, and one is working fine. i've swapped everything at least once and the problem is the Xbee.
it appears the firmware is fudged and now the modem can't communicate or upload new firmware. the problem is described very accurately in the following thread:

i've looked high and low and found about a dozen different answers to this question - none of which have worked.
i'm getting a little exasperated.
help!
