1. Any idea when the dev team will release it for the higher base bands on iphone 4 (2.10 etc)?

2. Can one install ultrasn0w having used Gevey sim previously? Will i have to remove the gever sim (and put in the normal sim tray) or can i install it with gevey sim still inside my phone?

thanks

@fasterpony how is your guide any more useful than the existing (and well respected) guides at places like iclarified? Additionally there are no "new" steps involved in the ultrasn0w 1.2.1 unlock, so why do we need a separate guide for this?

As I have said often here, we welcome useful contributions directly on hackint0sh, not links to re-hashed news/guides on a site you are trying to promote.
