Hi DJFuscao,

I have an HTC Tytn that I regularly use in Brazil (Sao Paulo) since oct 2006.
I´m not sure if I will be really able to help you, but I´ll try to give you at least some information about my experience.

I believe that sometimes autodetect network does not work properly. You may try to change these settings:
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your Network type: change this to GSM
- Settings-->(Personal Tab)-->Phone-->(Band tab)--> Select your GSM/UMTS band: GSM(900+1800)+UMTS(2100)

I have also experienced some problems some months ago when VIVO activated their GSM network. It simply stopped working, kept searching but did not find TIM´s network.
What I have done then:
- I have changed from Automatic Network Selection to Manual (you will find this option on "Settings-->(Personal Tab)-->Phone-->(Network tab)--> Network Selection".
- then I tried to click on Find Network on the same screen
- I chose TIM from the list
It has not worked at the first atempt because there were some different options for TIM on the list but it has eventually worked.

Another thing I would check is if it works with any other GSM carrier from Brazil. If you can borrow a SIM from some friend this could also give you some clue.
