Re: Will my phone buzz?
If you remove the two tork screws and remove the front cover you will se the board rev. In anycase if you have A5 or A6 you are susceptible to the buzz issue. If you bought 900 and dont experience it it is likely that you are communicating on 1900 which doesnt, according to anecdotal reports, suffer from the buzz symptoms Shachar Shemesh wrote: > Timo Juhani Lindfors wrote: >> Shachar Shemesh writes: >> >>> Can anyone tell me how I can find out?

I didn't say A6 would not need a fix, only that A5 needs one :-) ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

It _is_ read from the hardware by the kernel.

Easy enough. Unscrew the two screws, remove the front cover and check the area left of the mic. If there isn't a huge (relatively - 3.2 mm by 1.6 mm or more) capacitor left of or above the small resistors and capacitors, then you don't have the buzz fix. Examples: http://anyotherkey.googlepages.com/c http://vanous.penguin.cz/files/om/SOP/ Note: This does not apply to the GTA02v8 which is buzz-fixed differently. Btw, do we really need two wiki pages for the same thing? https://wiki.openmoko.org/wiki/GSM_buzz https://wiki.openmoko.org/wiki/Buzz_Fix -- Rask Ingemann Lambertsen Danish law requires addresses in e-mail to be logged and stored for a year ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Will my phone buzz?
Hi all, I fairly recently bought a freerunner. My cellular provider uses 900MHz, and I (and my call partners) do not complain of any buzz. However, I understand that the buzz mostly happens with 1800 and 1900 cellular networks, and so the fact I hear no buzz does not mean my phone is buzz free. For the next few weeks I have high access to SMT soldering equipment and people who know how to work them. I'd prefer to find a way to find out whether my phone needs the buzz fix now (and how to apply it), rather than later (when I will have no capability to actually fix it). Can anyone tell me how I can find out? Is there some way to look at the board of a phone and tell whether it has the fix?
