This may not technically be hacking, but I thought people may know. I've never had an iphone so don't really know anything about them. If I can get access to someones iphone, can I also access their icloud storage? Is there a way to retrieve the password so I can check the account later, or if not is the storage automatically accessible via the phone? Any advice appreciated.

Bump. Also interested if the other things aren't possible in simply being able to retrieve their apple ID.

Thanks.

All apple users doesn not have an icloud account. I don't think having access to their phones will help you having access to their icloud account unless you find their pass stored in the iphone (maybe in safari ?).
If you are able to reset their pass bu using security questions, you'd be able to dl their backup with a lot of softwares, eppb is one as w34k mentionned.
Then you might find their pass in the backup (notes, text message, etc..) but it's gonna be useless because the user will probably resetting his pass too and apple does not allow a same pass within a year.
