Just a bit of nitpick to save you some trouble in the future. Brazil is not poor. Brazil is the seventh world economy, if you count the number of nations in north america and europe, being the seventh world economy is a great deal.
Also the division in 1st world and 3rd world is schewed upon today. Its akin to saying the N-word. There are much better, non-pejorative terms to be used.
Brazil is a part of the BRICS or the world emerging countries. Right now it is in a huge political crisis and on the verge of a coup but it is not a poor-3rd-world-nation, it is a the world seventh economy and also dictating tendency for many emerging countries and a continental power in the south.
That being said, you are completely correct that Brazilians love technology. Our smartphone revolution and expansion is awesome and we're keen to adopt new tech. Still more than half of the country doesn't have access to net infrastructure at their home and depends on cybercafes.
If you want some real data on the technology adoption and usage in the country you can use the metrics and indicators from CETIC[0] which is the Brazilian Institute for the study of information technology usage and adoption. Their reports are awesome and will give you a much greater insight on internet usage in the country.

PS: Sorry for the long rant, I work with digital inclusion and web literacy programs here in Brazil, unlocking new digital skills in low-income neighborhoods so I've been immersed in this type of thing for too long.
