Unwanted words in my dictionary

When i type "kev" i want to write kev - not keV
When i type "hun" i want to write hun - not Hun
When i type "i" i want to write i - not I

How am i able to stop my iphone from auto-correcting these words (and others)?
Without having to turn the full auto-correction feature off as I often mis-spell words and it is very useful for catching my mistakes.

As you can see these words are not 'misspelt' in the true sense of the word, it is just that the iphone always tries to add a capitol in where i would rather have lowercase. Turning auto-capitalization off only turns off the capitalization of words that begin sentences and not these words or names.

- kev is the abbreviation of kevin - i dont want to always have to tap the cancel prompt for keV every time i want to say that name.

- hun is the abbreviation of hunny / honey - but the iphone seems to think that hun deserves a capitol H even when it is not at the start of a sentence.

- I would like to type a lowercase i - as i think the the uppercase I looks too much like a 1.

Thanks,
Fraser.
