How can I transfer WiFi passwords to new iPhone?

As I travel extensively I have a lot of WiFi passwords on my iPhone 3GS (iOS 4.3.5). When the iPhone 5 comes out, I want to transfer these passwords over. When I transfer all the apps, settings, etc. will the WiFi passwords copy over as well?

If not, I wonder if I can jailbreak my iPhone and use one of those apps that will unmask the WiFi passwords. I tried to downgrade to 4.3.3 in order to jailbreak, but I got stuck (I think) because I don't have SHSH blobs.

Or can I just copy over some encryped file on the iPhone 3GS filesystem to the iPhone 5? What is important is that I can use the WiFi connnections on the iPhone 5. Being able to see what the passwords actually are is not as important.

If you restore from backup the passwords will be saved and wifis will autojoin.

WiFi Pass/Passwords is a cydia app that shows all your stored wifi passwords. You can then take a screenshot and use that to transfer all the passwords to your new idevice

So first I should probably upgrade my iPhone 3GS to iOS 5 when it comes out.. and then back that up and restore onto the iPhone 5.. So is it generally possible to backup and restore onto completely different hardware releases? For example backup iPhone 2, restore onto iPhone 4... and so on without issues?

I downloaded WiFi Pass 1.1 from the app store but that is in some foreign language and I guess the right US carrier version would need a jailbroken phone.

well, if you are not jailbroken at the moment then you cannot download cydia apps. The cydia app Wifi Passwords is what I was recommending.
