Gingerbread!?

According to the official Amy-B thread that dell will provide a 2.2 update, but what about gingerbread(rumor said the sdk will be out soon)? Will dell follow the update path to provide us the gingerbread update too? Or is there a cut off point for dell streak support?

ps by the way just want to know is there FM radio and tethering fuction in 2.2 update?(given that they won't get blocked for some crazy service provider....)

thanks for answering :)
