Apple recently patched a major security flaw for iOS, and it also affects OS X. But until they release a fix, which the company says is soon, here are some of the apps you should avoid using on a public Wi-Fi.

The list comes from researcher Ashkan Soltani and you'd better not use these apps in a public Wi-Fi, because it leaves you susceptible to a "man in the middle" attack.

In addition to Safari, according to Soltani's findings, you should avoid using the following on a shared network:

• Calendar
• Facetime
• Keynote
• Twitter
• Mail
• iBooks
• Software Update
