I see your problem. I don't exactly know why, but unless you have somewhere between 1.25 to 1.5GBOf free space on your phone, updates will fail. I have had a couple of instances of this with my 620. Hope that helps.
thank u very much ..still I didnt updated my phone ...i will try to go to nearby Nokia Care and get it updated by them
