You may already know, that you don't have to use iTunes to manage iPod, iPhone or iPad. When searching for iTunes Alternatives it's very likely that you'll find a dozen of apps promising to manage your iPhone independently from iTunes. The software that I use is called CopyTrans Manager and you can find it here:
Free iTunes replacement to manage iPhone without iTunes
So far, so good. Did you also know that iPhone, iPod Touch and iPad require drivers to be recognized by your PC? These drivers are installed with a fresh copy of iTunes, meaning you need to install iTunes, QuickTime etc. to use your iPhone with your PC. As many people consider iTunes to be bloatware, you may wish to use your iPhone without having to install iTunes. That's why you can use the CopyTrans Drivers Installer.
This little free app installs all drivers and you'll finally be able to use your iPhone entirely without iTunes.
