I don't understand what you had an issue with here? Legally it's completely in the clear (see first sale doctrine) and morally I'm not sure how it's any different than, say, the startups making IBM compatibles back in the 80's.
Are you referring to the baked in default APN's for different MCC/MNC combinations? Yeah those were/are quite annoying to have around if they were out of date. (I think there might be auto-update of these now, but that obviously requires a network connection)
Or are you referring to actual radio config partitions on the flash? (Where one was able in the past on many models, flip bits in order to activate different cell bands)
The former being janky and security risk, the latter being somewhat illegal.
Why? Do you consider contempt of business model to be immoral? Or are you saying the phones were stolen and not just gray-market?
Paraguay is about 20% more, Argentina 100 to 200%, and Brazil 30 to 40% more.
Anything that is high end costs much more here due to a combination of tarrifs, reduced volume and the people who are wealthy not caring.
Read up on Ciduad Del Este, it’s basically the electronics hub for the southern cone where electronics are smuggled into Brazil and Argentina. Beef and eggs from Argentina get smuggled into Brazil and PY.
Anything that you were doing pales in comparison to what everyone here is doing.
It should be illegal to impose such terms on anyone who purchases anything from you.
Freeing those phones was a virtuous act, even if done for self interested reasons.
I'm talking from a corporation/carrier side that let this happen to consumers. If you sign to terms of a contract that gives you special access to phones to sell in your region and then you just go and break that contract that doesn't seem right to me. To be clear I don't think downstream consumers did something wrong.
Sounds like you did god's work.
