Might i suggest getting a used pixel from swappa or on ebay instead?
The one att gives you will most likely be carrier and bootloader locked for a period of 30 or 90 days i forget which but its fairly common for providers to do this to prevent folks from getting a cheap subsidized phone and then dropping the contract. So youll probably be able to flash graphene eventually but there woukd be a wait.
Alternatively a used pixel 8 or 9 will come already unlockable and ready to go and cost less too.








Ive downloaded over 150k tracks from tidal using tidal dl and after a lot of testing the most theyve done to counter is rate limiting or blocking the IP i was using, but if you stick with reasonable limits of how quickly you are downloading tidal doesnt seem to care much.
