The X6 is a great example of after sales support from Nokia. When it was first released, the X6 firmware (for the first 32GB Comes with Music devices) was one of the weakest release firmwares of the Nokia's S60 5th Edition devices. Over time it has improved to become a strong device. I’ve been using it as my regular phone since release. While it has recently been retired by the C6-01's arrival, it’s an honourable retirement – the sort that could see it pressed into service at a moment's notice for other family members.
If you want to know how long Nokia support their phones (and not just the flagships) then take heart in the story of the X6. *
