PS1, Line 15: The mobile app does not care, and will happily work even with fn+3.
you mean tn+3 here?
no, actual frame advance, 3
frames in advance.

PS1:
So if I understand correctly this adds a let's say
~0. […]
well this is my attempt to get your gprs side to give me tx bursts much
earlier, because right now they arrive very late. 2ts advance just is a value that appears
to "work", while 1fn breaks it.
I need tx bursts as soon as possible, and I'm currently getting bursts 0 ts in
advance, with only the rx/tx offset of 3ts so save me, and if those bursts are just
slightly delayed it's too late.

PS1, Line 261: burstTime.incTN(2);
just to make sure, incTN(2) on FN=X TN=7 ends up with
FN=X+1 TN=1, right?
yes, that is what the magic gsmtime class does.
