Silicon Valley South?

Potentially, says The Huffington Post who tags São Paulo as an "emerging tech epicenter."  Actually they mention specifically Campinas which is outside the city proper.  Maybe so, but I have a hard time getting my cell phone to work and experience lots of wonky internet (except at the university which has great internet).  I have been told that Telephonica has inadequate infrastructure for their residential internet service, not what you'd expect for an emerging tech epicenter.
