Older generation iPhone models, such as the original iPhone and the iPhone 3G, cannot be upgraded beyond iOS 3.1.3 and 4.2.1 respectively. With these obsolete or vintage Apple iPhone models, it can be difficult to remove notes because they use different syncing protocols. The iPhone 3GS and later can sync notes easily using iCloud, but previous generation iPhone notes will need to be synced to an email account, through the iTunes software or manually emailed.
