While most owners of iPhone, iPad or any other iOS device usually use iTunes to manage all their apps and media, there are definitely some drawbacks when using Appleâs application. The main one of course is that you can only use iTunes to transfer apps to an iPhone or iOS device that has been linked to your iTunes account on your computer. If you try to transfer an app to your iPhone or iOS device using another computer, iTunes will try to sync all content from that computer, erasing your iPhoneâs content in the process.
Thankfully, with the help of iTools â a very nice, free application for both Windows and the Mac that debuted not long ago â you can now transfer apps to your iPhone/iPod/iPad from just about any computer. Weâve already talked about iTools in our post on adding custom songs and ringtones to iPhone without iTunes.
Here is what you will need:

Alternatively, you could just drag the app file to the iToolsâ main window.
You will see a message that reads âInstalling program, Please waitâ, and after a few seconds the application will be successfully installed and will show up both on iToolsâ main window and on your iPhone/iPod/iPad.
