I plan to get a new iPhone 6S plus when it's released. I know it will be a while before the jb for it is released, though I know very little about jb in general. The things I am most interested in are being able to use my Unlimited data for tethering with my verizon account, using two apps at the same time on the screen similar to what can now be done on an iPad, and maybe just having a calendar widget and list of things to do widget on my home screens like can be done with android. 1. Can the jb let you use any apps on the screen at the same time or is it limited to only certain apps? 2. Are there only certain widgets that can be used with a jb or can I somehow make a calendar widget and one for my trello to do list etc. 3. Does doing any of this compromise my security? Most important to me is that by doing the jb, I can feel confident in using my device the same way I do before the jb without worrying about someone seeing my data, etc. Thanks.
