I currently use a Windows PC to manage the music and apps etc. on my iPhone 4 manually. I know, Windows but I need it for my university course.
I want to transfer the manual management of my iPhone to my Toshiba laptop for ease of remote access etc. I understand that in order to do so I must first erase the data on my iPhone and then use only the music data present on my laptop. I realise you can change iTunes settings to stop these devices syncing automatically, but I'm not interested in simply charging my iPhone from the laptop, I need to update it and manage music etc. My problem is the large number of (mostly medical) apps which were a pain in the ass to get on to my iPhone originally, due to specific permission being required to use the app, with a serial code amongst other things being required. I don't know if there is a term for these more complex apps, but I have a few of them and it would be a nightmare to lose them. I would sacrifice the ease of access of using my laptop to manage my iPhone in order to keep them.
My question: Is there any way to use my laptop computer to manage the music etc. on my iPhone without losing my apps? I have authorized the laptop already, will my apps be retained and transferred easily from this new computer?
