Making your Twitter account public on an iPhone requires using the Safari app or another Web browser to access the Twitter website directly. The iPhone Twitter app doesn't include an option to remove protection from your tweets so that anyone can see them. Fortunately, Twitter has a mobile website that fits nicely on your iPhone screen.
Step 1
Tap the "Safari" icon on your iPhone's home screen to open the Web browser.
Step 2
Navigate to the Twitter website and sign in to your account. The website detects that you're on an iPhone and loads the mobile version of the website.
Step 3
Tap the "Me" icon, and then tap the cog wheel icon.
Step 4
Tap "Settings" on the Account pane, and then tap "Edit" next to "Account & Privacy."
Step 5
Clear the check box next to "Protect My Tweets," and then re-enter your password.
Step 6
Tap the "Save" button to make your account public. All of your past and future tweets become searchable and viewable to everyone.
