To get the latest Salesforce functionality on your device, search the App Store for Salesforce1.
Salesforce Classic’s look and feel have been updated to comply with iOS 7 requirements, but the latest Salesforce mobile functionality is available only in Salesforce1.
Salesforce Classic is built on our classic user interface which does not include Chatter or other recent enhancements.
Salesforce Classic gives you access to your Salesforce information on your iPhone. Choose between:
FREE VERSION (also referred to as Mobile Lite)
Free for ALL salesforce.com customers (all license types).
• Access standard CRM data from your device
• Have your Salesforce Admin enable Mobile Lite for your organization
Requires Performance Edition, Unlimited Edition, or add-on mobile license
• Customizable with mobile access to custom objects and configurations
Salesforce Classic supports devices running iOS version 7.x.
Salesforce Classic device support is based primarily on operating system version. Carrier / model / OS combinations are not individually certified. It may be possible for newer devices with unsupported operating systems to download and install the Salesforce Classic app, but they should not be considered supported configurations until the operating system version is listed as officially supported.
