I spoke with RIM management about the Attendee units that fail. Anyone that has a bad unit needs to send me their contact information and I will pass it on to the right party at RIM. RIM will take care of any attendee defective units. I have requested permission to post the contact information and as soon as I get permission I will post it in this thread. In the meantime, PM me if you have a deffective unit with your contact info and I will send it in for you. I inquired about unlock codes for attendee units but do not have an answer for you yet.
