Apple Inc. this week said more than 25 million customers are using the new iOS 5 mobile platform in the first five days of release.
In addition, more than 20 million customers have signed up for iCloud, a free cloud services solution.
The new mobile software includes features like a Notification Center, iMessage to send unlimited text messages via Wi-Fi or 3G, Newsstand to organize subscriptions, Reminders, Twitter integration, new Camera features, and software updates without connectivity to a computer.
iCloud, released this month, is a free cloud online storage service for data backup, syncing, and access across devices. iCloud requires iOS 5 and iTunes 10.5.
iTunes 10.5, which is required to upgrade to iOS 5, includes new iTunes in the Clouds functionality to store purchased content to the iCloud service and push to all devices, new Wi-Fi syncing functionality, and support for the iTunes Match service to add iCloud storage of imported CDs at $24.99 per year.
