i think so, but i'll have to defer to their response later. sorry you're talking with the relative dummy. thx for letting me know your situation
UPDATE. our tech said he did delete the vendor .xml file, still apparently failed, and declined to spend more it time on this before at&t approves a new os. short version, i'm probably going to need to give up until at&t approves ( and puts online under http://www.wireless.att.com/bbdownloads
) a new OS for the 8820. (maybe that won't be until at&t makes the bold available...) thx again for the offer of help and sorry i couldn't take you up.
