"I'm not sure about that" vs "I'm not so sure about that"

Both phrases are correct and commonly used in English. The choice between 'i'm not sure about that' and 'i'm not so sure about that' depends on the speaker's level of certainty or emphasis. The addition of 'so' in the second phrase adds a slight emphasis on the uncertainty.
