please tell me a simple way to upload all info from my IPhone so I can get a new IPhone

A backup, using iTunes or iCloud. Import your photos to the computer using the operating system import utility for safe keeping, even though they are part of the backup, and if possible, sync your calendar and contacts to a supported application, either on the computer or cloud service for safe keeping as well.

You can create a backup in iCloud, you cannot just upload content to iCloud. See this support document to see what is backed up in iCloud. iCloud: iCloud storage and backup overview

Transfer content from an iPhone, iPad, or iPod touch to a new device - Apple Support

You're welcome.
