I've found (and confirmed on here) that the English (UK) keyboard doesn't auto-correct a lot of words the way the English (US) keyboard does - it's mostly things like capitalising "I" and changing "im" to "I'm".
If I want these corrected properly I have to use the US keyboard, but then I have to put up with wrongly spelt words all the time (), so does anyone know if there are updates on the way to fix this?
This was one of the first annoyances I had when switching from WP7 to WP8. I was also used to typing "i" an "im" and having it auto corrected. I miss that.
