If various online reports are to be believed, both the Nokia E55 and E52 has received firmware updates thus putting the software version at 031.012 - up from the previous v21. The 7MB update, which is said to contain bug fixes rather than new features, is allegedly be live via OTA (over the air).
Not surprisingly Nokia Care UK, and their unnamed outsourced UK-based third party support and service partner, has yet to make available the update for UK destined unbranded sim-free E55. I have tried updating this morning but to no luck. I made a mistake last month of applying the v22 update which caused my then super stable E55 to something that is a bit less stable, so I am quite anxious to try out v31.
