IPhone 5s ios 8.2 jailbreak without using a computer? How do i do this?

I do not think you can but the best thing is to call apple there help is great and free.

Unless you were using an online data backup service such as what Google provides for Android phones or a third-party backup program, unfortunately your data is gone along with the phone. Cell providers usually have some sort of contact backup service but you would have to have already been subscribed to and using the service to retrieve your contacts and download them to a new device. Apple has backup services similar to Google's Android phone backup but if you had an iPhone you would have needed to already be subscribed to the service to have any data available for your new device. I wish I had better news for you.

Just one of the hundreds sites telling how to jail break an iPhone.
You have tethered and untethered, one you alway need a computer if you want to react the phone the other can be rewetted without computer. Onch broken, you need to install a Cydia (like) app store, and there you also have to pay for the apps. Only very smart hackers succeed in getting free apps.
I think you better first read the Wikipedia page about jailbreak, before you start breaking.

Hi there,

Currently there is no way to jailbreak iOS 7 on any iPhones yet. The jailbreak developer are currently at work and it will take some time for them to release it for public use.

Hope this helps

I'm afraid you probably have a bad sim. I had a similar problem with a sony ericsson. phone would reject the sim, but a telco rep was able to recover data
