Only stumbled across it now.
May be fun to decipher for some of you.
It sure was for me.
Good luck!
Spoilers start below this line.
It reads:

Tip 1:
Are there any reoccoring words in the text?
Answer:
Yes: yfi - thrice; pcm - once in isolated form, once as pcm'vx; xabs - twice with one word in between;
Xvxwdzs - twice; t - twice; kvw - twice, once as kvwvx; hn - twice + hnwej
Tip 2:
Looking for words that contain an apostrophe might be very helplful.
They are:
A'q, Zh'k, fz', pcm'vx, I'cz, Gsq'l and Rglmobszcf'w
Tip 3:
Pay special attention to one letter words. They most likely translate to I or a or, less likely, to u or r.
More help:
kv and xa appear very frequently at the beginning of words.
uvtvkzby, rhmhzby and ggqxmhzby all end in zby.
Critical hint:
How can you explain weird double letters as in ggqxmhzby and llx?
Partly solved:
It's a polyalphabetic cipher.
More:
It's a Vigenère cipher.
Almost done:
xabs, sil xabs should give you a good idea of how long the key word is.
Alternatively, you could count the letters between the two occurances of Xvxwdzs (154) and then do a prime factorization.
Solution:
It's a Vigenère cipher and the key word is Rosetta.
