Iphone freezing at beginning of text message

Question

my brand new iphone 3gs is freezing as soon as i start typing in the name of a person to text message. it is fine if i select an old message and then start from there, or go to a contact and click "text message." But if i just start on a blank text and start typing in someone's name like "Sara", it will freeze on the S and nothing happens for a good 20 seconds or until i hit the home button.
this had started happening with my old 1st generation iphone too, which is why i just upgraded to the 32gb 3GS!! And it's still happening!
Is anyone having this problem too?? Should I return the phone? But if it happened to my old phone, I'm thinking it's the software not the phone...
Please help, this is very frustrating.

Probably not. Some of the Unicode encoding types... the list is here:
http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html
support the BOM, so you'd only need to know that it's UnicodeBig or UnicodeLittle or whatever it really is.
Of course, if you don't know what it is, that is a problem. You can probably assume the BOM bytes are actually that, but technically, you can't generally infer any particular encoding type by just reading the file. I mean, who's to say that a file is UTF-8 encoded or ISO8859-1? Yes, if it is UTF-8, and it includes chars that are of multi-byte sets (Chinese, for example), then many characters, if read as ISO8859-1, would look on screen like gibberish. But from the standpoint of reading a file at the character level, Java doesn't care and can't know.
So to really know, you would either have to know ahead of time what the encoding is, or do some analysis of the data to see if it's likely 1 or the other, which is probably hard to do cuz it would require some sort of natural language knowledge.
