Every time I typed the word “as” into my iPad (and iPod touch), it would auto-correct to “A’s”. Drove me absolutely nuts!
Turns out it was using my Address Book as an auto-correct data source and I still had “Oakland A’s Tickets” in there from when I lived in the Bay Area.
I removed this entry from my Address Book, and that seems to have fixed it. Of course, if I’d wanted to keep that entry in my Address Book, this wouldn’t have been such a convenient work-around.
It seems to me that 
correcting 
an accurately spelled dictionary word to a word in a name in an address book may not be the right order of preference for an auto-correct algorithm.
I have had the same situation – Is this a fix that they will be coming out with in the next software update?
The inability to edit the auto correct dictionary is one of the minor daily irritants I have with the iPhone.
Hey, I had the sameissue and fixed it the same way, but it only fixed for some apps. Mail won’t cooperate. Reset the dictionary, searched the phone for any stray “A’s”. All to no avail. Any ideas?
Same issue here. I had A’s for adam’s in my phone book and just took it out. Thank god it fixed my text message app but safari and mail are still doing it
I have the same issue except I have it with the word “it” as in information technology. Every time I type it, it gets capitalized. Urg!
If you bring up a mail and type a nonsense sentence that has the word that is being corrected in it about ten times, each time the iPad tries to correct simply dismiss it’s attempt by pressing the little blue cross. Once you have done this about ten times, the iPad then assumes the new spelling is correct.
I find it hard to consider that a “solution”.
