Apple will likely unveil their new iPhone line on Tuesday, Sept. 10 at the company's headquarters in Cupertino, Calif.

The corporation released invitations on Tuesday, Sept. 3, featuring the Apple logo in the center surrounding by multiple colorful circles. Below the logo the invitation says, "This should brighten everyone's day."

There has been no confirmation as to what Apple will unveil on Sept. 10. The prevailing rumor is that they will showcase the iPhone 5S in addition to other similar products. The new iPhone 5S is rumored to have a 128GB option in addition to an improved low-light camera performance and memory bandwidth.

Apple may also unveil the new iPhone 5C, a less expensive phone that comes in a variety of colors. This would line up with the invitation, which features multiple colors.

The company may also be revealing more details about iTunes radio, which TechCrunch is expecting to be made available to U.S. users with the new iOS 7. The website also predicted that iOS 7 will be unveiled in late September along with the release of the new iPhones.

The news that Apple will be unveiling their new line of products on Sept. 10 means there is competition for Intel, which is intent on having their own conference on the same day. The Intel Developer Forum will be held on Sept. 10 featuring Intel CEO Brian Krzanich and president Renée James.

Apple CEO Tim Cook will be making his own presentation at the Apple conference.
