Thanks for the info. While I'm good at soldering, I'd prefer to wait
for an "A7" revision if that happens. Searching the hardware archives
mentioned there might be one:


I realize it may take a while. I'm guessing A7, if it happens, may
also have other updates which may help some other issues of the phone.
Looking at the hardware wiki, I see no list of confirmed or even
suspected hardware issues. My interest in openmoko is kernel and
bootloader related, and there's just somethings that can't be fixed in
hardware despite the steady stream of patches I see on the kernel
list. So I'm unclear if some issues like suspend, battery life amd
missed calls are perhaps hardware issues? Just trying to make an
informed choice between buying now or later.

Best regards,
