My iLiad is back but w/o new paid back cover.
I got no explanation via e-mail or printend paper why this happend.
So I had to call iRex Support via phone.
They excused for this [...], promised [as I understood] that the others (I am not alone) will get e-mails.
Some spare parts [due high demand] are missing: attachment somehow for cover.
All the best! Hope you are not one of the those who get iLiad with old cover.
