Winpwn 2.5 is out and does quite a few things. It pwns, it quickpwns, it handles all the latest firmwares. Here are a series of guides to help you.
To help you pick which mode to use, use this:
Basic Mode - This is “easy” mode and uses default settings. It asks you questions as you need and eliminates your need to make complicated decisions. This requires a restore. You will build a custom firmware image as part of the process.
Expert Mode - This is like basic mode but gives you more control over the process. Since it is expert mode, you are expected to know what you are doing. I will cover a few points but I will not baby step through this with a full guide. Honestely, if you need such a guide, you should not be using expert mode.
Quickpwn - This mode will do a pwning of your device without a restore. It is for phones that are already working and you just want to jailbreak. If you have to restore anyway, use one of the other modes instead.
