they had found some manuscripts in yemen in the 70's that are extremely different from the quran today. if you do a little googling you can find some pics of the arabic text compared to that of it today.
did u add that part 'extremely different' ??? hahahah
please read
http://www.islamic-awareness.org/Quran/Text/Mss/
before you make such claims.
also I would suggest to read on this thread, since your claim has been made long time before u.

as a Christian, i would immedately(and still do) think that the quran is corrupt, because it's different then what it used to be.
ok let's rearrange the statement, how about this,
"as an Ignorant, i would immedately(and still do) think that the quran is corrupt, because it's different then what it used to be."
You don't know about the history of Qur'an, and the different dialects it was revealed, that's why it looks corrupted to you

when in fact it's not. again I am recommending u to read on the two above links
BUT, perhaps maybe the person who wrote it just made some mistakes?when you record something, you are always liable of messing up here or there.
what book are u talking here about? the bible?
the quran is shorter then the New Testament. it is a very very short book. and so yeah, it's not a huge surprise that there are not a lot of contradictions. the NT has many different authors.. because many people knew Jesus and were inspired by the Holy Spirit. and it has 0 contradictions. of course some muslims will say "yes it does" but with just a little context looking and such, there really is no contradictions. and muslims obviously don't take the Nt as being from God, because it is supposingly corrupt.
first, Qur'an is a 600 pages, now does that give you an excuse to say "there is no contradiction" ?????????
second,
even if the book is 10000 pages, from God , it should not have contradictions.
third, bible of course has contradictions cuz it was written by humans.
fourth, Qur'an is 600 pages, but what it holds inside, not all the books of the world would equal it.
18:109. Say: "If the ocean were ink (wherewith to write out) the words of my Lord, sooner would the ocean be exhausted than would the words of my Lord, even if we added another ocean like it, for its aid."
also, go look into the buddhist texts.. find me a signle contradiction in buddhist writings! or baha'i, especially. if you add up the baha'i writings, there are over 95 times that of the quran. and so far, people have only found 3 contradictions, and they really are not conradictions!
let that book be popular as Bible and Qur'an is, and we would see how good it is

.
or open up a harry potter book.. harry potter books are prolly 3 or 4 times the size of quran (usually just a little smaller then Bible)... find me some contradictions! go ahead, look!
what is harry potter? a kid book?
sci-fi??? which is just read by people??
let the people study it , and we shall see what's inside, even it is just sci-fi.
it is no surprise what so ever that there are no contradictions in the quran. not a surprise.
Yes

, bc Allah swt sent it,
4:82. Do they not consider the Qur'an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy.
so, you know that Qur'an doesn't have any contradictions, but you are giving yourself an excuse for it.
2:23. And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true.
2:24. But if ye cannot- and of a surety ye cannot- then fear the Fire whose fuel is men and stones,- which is prepared for those who reject Faith.
