Thanks for the response!
(sorry, I don't know how to quote text, so I will answer one by one here
without your quoted text).
I e-mailed the developers yesterday and I'm waiting for a response.
I tried copying the CM firmware into my Replicant but couldn't get the WiFi
to work. The files under system/vendor/firmware on CM (the ones related to
Broadcom) are different files than the ones listed on the Replicant website).
I downloaded a stock ROM with the intention of extracting the proprietary
firmware from that but they are .img files and I couldn't figure out how to
unpack or mount them so I could see the directory tree.
As far as I could see, Samsung does not provide the stock ROM. They can be
found elsewhere, but none of them include a .pit file (to re-partition). I am
weary of trying to flash the stock ROM without a .pit file. As you can
probably tell, I am not knowledgeable on this subject. It might work without
a .pit file...it might not. I didn't want to risk bricking one of the phones
to test.
I will try their IRC channel for the 3G. They make it clear they will not
help with the proprietary WiFi firmware (which I can understand). The forum
is quite empty. I may try to post there regarding 3G as well. I kind of wish
they provided support for the WiFi since it is really quite necessary. I
curse Broadcom and not Replicant though.
I also noticed on the homescreen of replicant that it still includes the
Google search box. I would like to change that to duckduckgo but it seems it
is also used to search within the phone, so I'm not sure if this is possible.
I haven't done much to look for a solution to this, since without any
networking all I do is make and receive calls. I don't use a cell phone much
anyway, but the Note was for my wife and she uses her phone more than I
do...she's...hmmm...not so happy with me right now :/
