Rejected from Apple store

First time when I uploaded to App store, there was no problem. Then I uploaded the next one for version up, but I got rejected.

This is the message that I've got, but I have no clue where to fix.

Before you Submit

Your app does not comply with the Guidelines for Using Apple's Trademarks and Copyrights. Specifically, your app includes:

The term iOS in the device name.

Next Steps

Please revise your app and its metadata to address these trademark issues.

For your convenience, we've provided the relevant section/s of the Guidelines for Using Apple's Trademarks and Copyrights:

Product Names Guidelines

You may use Apple, iPhone, or any other Apple word mark (but not the Apple Logo or other Apple-owned graphic symbol/logo) in a referential phrase on packaging or promotional/advertising materials to describe that the third party product is compatible with the referenced Apple product or technology, provided they comply with the following requirements:

• The Apple word mark is not part of the product name.
• The Apple word mark is used in a referential phrase such as "runs on", "for use with", "for", or "compatible with".
• The Apple word mark appears less prominent than the product name.
• The product is in fact compatible with, or otherwise works with, the referenced Apple product.
• The reference to Apple does not create a sense of endorsement, sponsorship, or false association with Apple or Apple products or services.
• The use does not show Apple or its products in a false or derogatory light.

In other words, whether appearing on the application itself and/or in marketing materials, the word iPhone may be used as a descriptor, but not as part of the product name.
