TBH this is the worst BETA experience I have ever had. Never had HTC or OnePlus send me an email at the end saying basically lots of luck getting a stable approved update on your unlocked device.
And both dates were wrong. T-Mobile is incompetent. The cool thing about having an unlocked device is I can just switch to Verizon. They seem to be able to do the simple task of updating their phones. T-mobile support read my message asking for an explanation for the delay and they responded "good news the fold 3 is in stock!" 🙄
