you can use this programm if you want to avoid iTunes:
http://download.cnet.com/CopyTrans-Driv ... ?tag=mncolit will install all the components of iTunes MM will need to "see" the iPod/iPhone but not the entire programm.
An other solution would be:
1. Download the iTunesSetup.exe (or iTunes64Setup.exe is you're using 64-bit) file
2. Rename the .exe to .msi
3. Get 7-Zip to extract only what you need from the iTunes installer archive.
4. Open up the zipped file (right click 7-zip -> Open Archive, open .rsrc directory) and extract AppleMobileDeviceSupport.msi (AppleMobileDeviceSupport64.msi for 64-bit), and QuickTime.msi (Quicktime lite recommended instead)
4.1 iTunes v9.1 - In the .rsrc directory, opend the RCDATA directory and extract the CABINET file. Rename it to amds.cab, open that file again with 7Zip, and then extract the .msi files as above.
5. Install these files
