Taking all of your hints into account, I come to the conclusion that the answer is

4 and 9


Some of the numbers in the sequence are bracketed. I think that those are the numbers that need to be skipped to construct the classic 'Haus vom Nikolaus' (https://math.stackexchange.com/questions/497342/das-ist-das-haus-vom-nikolaus-and-euler-cycle) on a smartphone's numeric keypad (second hint: "Old meets modern technology"). But up until now it's just an assumption, because you didn't answer my question (yet). Why do I think of the "Haus vom Nikolaus" (house of Nikolaus)? Well, that's because of your first hint "It is a cool number sequence puzzle". The house of Nikolaus (or Santa Claus) is located at a very cold place on planet earth. To support my point of view, I created a gif illustrating what I mean and how it (seemingly) fits perfectly. enter image description here

    $\begingroup$ @user477343 Thank you :-) Well ... all the given numbers lie between 2 (minimum) and 9 (maximum). Some of them are bracketed (which seemed quite interesting) and this sequence is limited! Toying with some ideas and taking all the given hints into account finally led me to this conclusion :-) $\endgroup$ – André Mar 28 '18 at 22:56
