It looks as though Apple have paid $21 million to settle a copyright dispute with SBB over their iconic railway clock, reports Mobile Geeks. At the time of iOS 6's launch, the news started floating out that there was an agreement between SBB and Apple.
This agreement didn't come with a monetary value attached to it, but The Daily News have reported that neither party would disclose whether the payment was above 20 million Swiss francs. Apple would've been stuck between a rock and a hard place with this decision.
On one hand, Apple were very quick to just throw a huge sum at SBB - but there could've been a nasty lawsuit and a ban on any device which sports iOS 6 out of the box - such as the iPhone 5. On the other hand, they could've reworked the design but this would've taken both time and money.
