I too just spoke to Support, and they informed me that the Transparent backcovers with orders from December will be delivered in the first half of March. They also promised that an email regarding the delay will be sent today or tomorrow. I really do hope these promises are not broken as those that came before.
They informed me that the alternative backcover solution was only offered to October (and perhaps November) customers, and no solution had been created for the December customers. He could not tell me when the new batch of transparent covers was expected, it seemed nobody knew, or they are not sharing the information.
I am most dissapointed by the fact that Fairphone does not appear to be communicating at all, they keep making promises they don’t keep and in updates they consistently report untruths.
Maybe they should extend the alternative backcover solution to December?
