Join a wireless network with an non-typable password iOS devices
The WPA password for my employer's wireless network contains a backtick (`), which is currently not supported by any of my iPhone/iPod Touch keyboards (I'm using the latest firmware at the time of this writing, which is v2.1.1). This prevented me from synchronizing information over-the-air while at work.

The iPhone Configuration Utility, available on Apple's iPhone enterprise support page, lets you create wireless network configurations and send them to your iPhone or iPod Touch. However, it only contains a field for entering the SSID, not the network password. Thankfully, Apple's Enterprise Deployment Guide (740KB PDF) references a Password key that we can take advantage of to send the right password to your iPhone or iPod Touch.

This hint will require your iPod or iPhone to have some kind of wireless network access to begin with. But it also requires a Mac or PC, so perhaps you can set it up to share a wired internet connection over the air (more on that here).

Here's the way to resolve this:
  1. Download the iPhone Configuration Utility from Apple's iPhone enterprise support page.
  2. Create a new configuration profile and enter your Wi-Fi settings.
  3. Export the configuration profile to your Desktop or any place that's convenient for you.
  4. If it's the wireless network's password that is causing problems, open the exported file in your favourite text editor. Insert the following after the part that specifies the SSID:
    <key>Password</key>
    <string>THE_WPA_PASSWORD</string>
    Note: I had to replace two characters in the password with XML entities (&lt; for <, and &amp; for &) to make this work.
  5. Email the config file as an attachment to an email address that is set up on your iPod or iPhone.
  6. Open said email on your iPod or iPhone, open the attachment, and touch Install.
From there, your iPhone or iPod should take care of the rest!

Compute Hexadecimal Password

ASCII passwords for WPA are hashed with the SSID to create a hexadecimal password anyway. I don't know the details of the PBKDF2 function, but I found a site that will do the conversion for you. Thereafter, you can just use the hexadecimal version of the password to connect.

Compute Hexadecimal Password

I have found a similar problem with my Macbook, having my employer a "ñ" in the WPA password. I just cannot input this non-ASCII character in the Airport utility (in fact, I tried using the airport command line utility with no luck). Introducing the hex equivalent would work?

No, that site will not work with non-ascii unicode characters. Technically, they aren't supposed to be used. This site seems to accept non-ascii characters in the passphrase. Give it a try. It takes forever, though you'll only need to do this once per network.

If only you'd answered my question on the Apple support forums when I posted it there, I wouldn't have had to go to that trouble : )

Or you could also jailbrake the phone and just change the keyboard plist file to include `

AFAIK firmware 2.1.1 hasn't been jailbroken yet. No?

I'm using an iPod Touch, which iTunes reports as having software version 2.1.1.

Does copying and pasting a ' from another application not work?

THANK YOU THANK YOU THANK YOU!

Under the 1.0 firmware, I got my iPhone on my home wifi network all of once. The first update wiped out my saved password, and I was never able to convince it to join again. I had high hopes with the 2.0 firmware, but they were immediately dashed. Switching from a Linksys WAP to a Time Capsule didn't help either. My home network has WPA protection and a 63-character random hex string for a password, and the wretched phone always claims that the password is wrong. Until now! Yay! This was so easy! Thank you!
