Its been long time I am checking for update in my NL620 but till today there is no amber update.... Some of my friends have same phone also doesn't get amber.... I don't think my phone details will help... I am from Kerala using idea network,( I don't know it may help)... As I called Nokia care here they don't know about amber update either..... I think some of guys from Andhra Pradesh updated to amber.... I will appreciate any useful replays.... Thank you guys for reading my post....
