Unlike the iPhone most of these updates are from the carrier. If the carrier is not ready to support this, most carriers delay the update. As to the samsung account I wonder if this works if you are the right person from ATT or such.
I'm trying to update my firmware from KE2 to KE7 on my Samsung Galaxy S2 phone.
I go to Settings > About Phone > Check for Update
'says I need a samsung account. No matter WHAT email address I enter, it says the account already exists. ( !!?? )
EDIT: ok I just tried again entering a completely bogus (random characters) email address and it let me sign up. Didn't accept any of my valid email accounts before that.
And of course... it says no updates available. GRRRR!
I know some blog said that you can do it via Kies Air, but you can't - there's no options for updating.
