Should I jailbreak my 6s?
In my personal opinion I say no.However: There are pros and cons to both which can be seen as helpful or hurtful for why you want to jailbreak your phone.Let’s start with the cons:You will allow all third party applications to access your data that is set to be off limits and inaccessible by Apple.If you care about security, don’t jailbreak. If you do, it will leave your iPhone open and vulnerable to malicious attacks.Your warranty will be voided. If something goes wrong during jailbreaking and it gets bricked (device becomes nonfunctional) it will not be covered by Apple and if this happens, you have a $700 piece of aluminum and glass that does nothing.Even if your iPhone does not get bricked if you bring it to an Apple Store the Geniuses will not give you assistance as soon as they realize it is jailbroken.Software updates do not come as fast as they do from Apple. You will need to wait until the jailbreak community comes out with a new iOS update for the phone.Battery will drain much quicker than normal due to the hacks being much less power efficient.Now for the pros:You have access to alternative App Stores and you are able to run emulators. You will also be able to uninstall the apps that are put onto your phone by default. (A feature like this will be coming in iOS 10.)You can customize the look and feel of the iPhone with tweaks and change the dock, status, and default app icons of apps. You can install apps that aren't available from the iTunes App Store.Tethering is an option now and this allows you to use your iPhone or cellular-enabled iPad as a broadband modem to connect your laptop to the Internet. If you want to know more you can find more on it here iPhone® WiFi Tethering and iPad®There are much more than just these that I have listed. I recommend reading more about them before making any major decisions.
