hi Dr Soidberg,

so when you docked your iphone with iOS5 to the DCM580, you can see the version upgraded v45?
If that's it, I think you have already done the upgrade.
If that's still a version before v45, then I guess you have to do it again...

Making sure that's the genuine file is important. As it is announced in the forum home page that, Philips is now having a server system issue... It's also mentioned by Cassandra here. I guess to make sure you have the right file, ask Cassandra to send you that directly...
