Actually, the B8 has a different processor with different capabilities the Alpha7 instead of the Alpha9, it is not a simple "port", and that is why a different fix must be created from scratch separately for those models.
Eh? They've already said that they will do it. This is not in doubt.
Eh nice to hear. I have been following this these posting for about 9 weeks or so now but nowhere I saw any confirmation that it will be offered officially. There are a few statements from the LG servicedesk but you probably know as well as I do that statements from them are very untrustworthy. Can you please tell me where LG really has stated that the update will come.
