From Reddit:
A bit late to post this, but it means that this phone has received 8 years of support (2011-2019), beating out the legendary HD2 with its 7 years (2009-2016) and becoming the phone with the longest unofficial support thus far (unless there is some other device with longer support, in that case, please inform me).

Huge credit to rINanDO for his amazing work!
I wonder how far we can go…
