iPhone 4 and Sky wireless

So, here I am. 2 months into a new flat and Sky have finally managed to get my broadband connected.
I’m running around the house madly hooking devices up to the wireless network and everything is grand… everything except my iPhone 4…

It can see the network but when I enter the WPA key it gives me a nice “Unable to join network” message.

Browsing the web for solutions finds such useful nuggets of wisdom, as “get a real phone”, etc.

Luckily there is a simple solution.

The CAPS lock function just didn’t do its job. Sky WPA passwords are all in capitals by default so of course I used the iPhone double-shift-tap to enable CAPS lock when entering the key, but for whatever reason that didn’t work.
Trying again, but using the tedious, tap-shift, tap-letter, tap-shift… method got me online.

Of course, I’m completely unable to reproduce it now. Forgetting the network and trying to rejoin using CAPS lock works fine…
