I'm trying to connect to a new network but when i type in the password to connect it says incorrect password. It connected to my iPad fine though. I'm trying to connect to a bt Wi-Fi.

Tnake sure you have caps on

Go to Settings > General > Reset > Reset network settings. And Restart your iPhone.

Thats because its an iphone.

Check if your caps locks on?
maybe there's a problem with your network?

or maybe its just your device and ios 6, never buy a new phone straight away, there's always problems plus ios 6 is full of bugs at the moment, when the new updates out then it might get fixed. I have a lot of bugs on my ipod cuz of ios6 but hopefully gets resolved soon
