Well, that's what they did with the first one (even though they could have let the Chinese manufacturer flash it as well). Also it's quite unclear when the Intex phone will go on sale so this phone might be in Jolla's responsibility software-wise. They might even use the feedback from this beta group to adjust the final Intex phone, as features like dual sim are completely new to SailfishOS.

Additionally, I think that Jolla might want to tie individual phones to developer's account to prevent resale, so this would again be better done in their facilities.

On the other hand, the "order cannot be changed" clause would suggest it could go straight from India, so we'll see. I still don't think Jolla will make much money (if any) on this device, though
