For those out there that have a Korean phone and feel compelled to send a text message (sms) to a friend in Korean but have been unable to find all the letters, heres some really useful info!!
The following is from KoreanWiki:
Anycall(Samsung) and EVER(KTFT) phones
Anycall and EVER (brand) phones use •, ㅡ and ㅣ to create vowels when text messaging.
Sky™ (brand) phones have a different style of text messaging. Unlike the standard way, you don't use • and ㅣ to create vowels.
The consonants are self explanatory, so the table below shows how to create all the Korean vowels
CYON(LG) and CanU(팬택&큐리텔) Phones
So there you go!
The above all comes from the totally awesome KoreanWikiProject.com
