If i jailbreak my iPhone, can i still backup my phone with iTunes?

I saw some amazing hacks with cydia, and I'm thinking of jailbreaking my device to benifit from those. My only concern however, is backup and restore, in case i change my phone or update to a new one.

Can i still use iTunes and iCloud to backup / sync data after the jailbreak?

Yes. But you can't backup the jailbreak files using iTunes. Try using iFunbox software.

Absolutely you can. You can do everything with you iphone as if it were not jailbroken, icloud, ituens, etc. The only thing that jailbreaking does is install the cydia App Store with allows you to install tweaks and apps not found in the App Store. If you are considering, I highly recommend going for it!

Yes, you can. But you should be careful in future about it. You should learn a lot about Iphone and iTunes. I'm giving you a website url, from visit there you can learn a lot about Iphone and it's uses/ it is very benifical to Iphone user. Best of luck.
