Is it possible to transfer music from ipad directly to iphone without using a PC?

I'm trying to decide if i should just purchase the ipad instead of the macbook pro, all i need to do is surf the web and be able to download music onto my device to transfer to my iphone.

I only have 1 idevice (my iPod) but if you have ios 5 or higher than I think if you sync with iCloud than you can transfer songs and whatnot. I'm not 100% sure cause I don't use iCloud. I'm at least 60% sure though. Hope this helps!

Have you thought about using Drobbox? I believe its the best option for you to access all of your music on any device you want to.

Yes, you not only can do it, but also easily do it. Just use the third part named transfer in http://www.istonsoft.com, you can get your target. There's http://www.istonsoft.com/transfer-ipad/ipad-music-transfer.html may uesful for you.

I often use iPad Manager to help me. It supports all iPad, iPad 2, iPhone, iPhone 4, iPhone 4s, iPod, iPod touch, etc. So you can use it to transfer files between these Apple devices.
