brought my iphone 3g from the states here and needed to get it unlocked, got a tip from a friend, went to the place, had a great experience, and just wrote up a recommendation for another friend, so here it is:
"the place is at Galeria rio de janeiro (an inside shopping area), the address is Cabildo 2370. Store #39 (cell phone accessory shop, 1 minute in, first floor, on the right) - a few blocks west from subte stop Juramento (Green line D) Its on the same street that the subway runs on, ie dont turn. So if you're walking west away from the subway once you get off, rio galeria rio de janeiro is on left side of street. 220 pesos to unlock my iphone 3g, no sure if they charge more/less for other versions of iphones, they say they can do it in about 2-3 hours, very nice family who owns the shop, open til 8ish mon-sat")
2 weeks later phone works great with movistar, bought a used nokia phone as well to switch sim cards for those nights I might be a litttle um tipsy.
