Can we use iphone without itunes?If there is other possibility plz inform me kindly.And how does the iso file related with iphones?

Answer 1

Sure, of course. Unless you never transfer music, videos, and other files from computer to iPhone.

You can download App from App store on your iPhone directly. You can update higher iOS on your iPhone via OTA directly. And about transferring files between iPhone and computer, I will recommend Leawo iTransfer as iTunes alternative. Because it is used for transferring files among iOS devices, iTunes and PCs, and it enables users to transfer various kinds of files without the sync of iTunes.

Answer 2

Can we use iphone without itunes?

Current iOS gadgets running iOS 5 (iPod Touch, iPhone, iPad) are fit for being independent gadgets. You needn't bother with a PC to utilize them. 

The expression "iTunes" can allude to two things... 

The iTunes application, which you appear to disagree with, and the iTunes store, where you purchase applications, music, motion pictures, and so forth.. 

You do not need to bother with iTunes (the application), yet you will think that its hard to abstain from utilizing iTunes (the store). 

iTunes (the application), makes it conceivable to utilize iTunes (the store) on your PC. This can give some comfort, however it isn't necessary. 

For whatever length of time that an iOS gadget can be connected to the Internet, you can actuate it without a PC or iTunes (the application).
