Pjiang: after reading your EAD blog, still confused.. please cla

when starting a job with a new company:

1. if I use EAD before receiving H1B transfer receipt, can I still use H1B when the transfer is approved?

2. if I use EAD before filing H1B transfer application, can I still file a H1B transfer and become H1B status when the transfer is approved?

Thanks.
