How to backup iphone without using itunes?

I'm new to the iphone and although I can operate the phone fairly well I'm really struggling to use itunes, I just find it really confusing. I have a jailbroken iphone with some music and a few apps on it. I want to make a backup but when I connect to itunes and try to sync it tells me it will delete all my apps/music/photos etc if I go ahead with the sync.

Also, how can I transfer music/photos/apps to my phone and from my phone to my pc? I can't seem to just drag and drop like I expected.

If anyone knows an easier way of doing this that doesn't involve itunes I'd be really grateful. I'd prefer a 'drag n drop' method but it needs to be quite basic please as I'm quite old and not very good with computer things.

Unable to send and receive messages on whatsapp?

2 days ago my whatsapp on my iPhone 4 was working fine, however the following morning I'm unable to send and receive messages from one particular contact. I'm able to send and receive messages on whatsapp from all of my other contacts. In the chat, the "last seen at… " was 2 days ago, however they were able to send and receive messages to their other contacts as well. We both have full signal, and we're both connected to the Internet. We've both turned our phones off and on and turned our Internet off and on. I have also deleted and reinstalled whatsapp but still have the same problem. When we try and send each other a message, only one tick is displayed. On the whatsapp FAQs, this means that's the message has been "delivered to the server" but not delivered to the recipients phone. On all other whatsapp chats, I get the two ticks with no problem. Finally, we both have the most recent version of whatsapp. I've also emailed whatsapp support and currently waiting for a response, but I'm not expecting a quick reply.

Added (1). And we haven't blocked each other either
