Same happened to me. It took all the data off my Bold but refused to put it on the Z10. The same thing happened when I tried to transfer the data using the media card. Read and verified it off the old device, but wouldn't put it all on the new one. Only some data made it over via the media card and sadly that didn't include my Contacts which had to be synched with my Gmail account to be able to get them over. A couple of evenings trying to organise it was frustrating but probably worth while. G picked up my Z10 on Wednesday at the BEF13 and in two days have come to love it.
