STATUS: SOLVED SEPTEMBER 8TH.
Some iPhone customers are having problems downloading Zipp/Zipp Mini speaker firmware via Libratone App for iPhone. Download stops at approx. 60%.
We are currently working to solve this problem and expect to have a solution during this week.
We apologize for any inconvenience this might cause you, and thank you for your patience.
Meanwhile - if you have access to an Android smartphone - feel free to download and upgrade firmware via Libratone App for Android.
