Can't install skype on android 2.2

I'm using http://www.midoblesim.com/product_info.php?manufacturers_id=&products_id=483 and i can't install skype.It says that it's not matching, but still it is downloading it from the market. I gived you that link becouse this isn't an original, android phone, it's some Chinese stuff. But however, how can i solve the problem and install skype and run it correctly ?
