i have a fake Nokia N99i actually its Toshibo TV-N99i, my mother gave it to me as a gift, and guess what i've been using it for more than a year already,  My Personal Commeent regarding the phone, 

PROs: can Play *.MP3, *.Wav, *.MP4 (vid), *.3gp, expandable memory (i'm using 2GB microSD, i think it is capable 'til 4GB), has Analog TV (love it during black outs ), bluetooth able, with FM radio, SMS, MMS, WAP/GPRS able, with 1.3 megapixel camera, Video recorder, Sound recorder, other N99i manufacturers have Ebook(capable of reading *.txt files), and in other China Phones (N100) you can record TV shows with the Analog TV while watchinf if you plan to watch it again, and lastly, you can change your voice - you can make your voice child-like, womanly, etc,  which is fun

CONs: too large ; dtoo flashy ; can't download and install games; if you will view *.gif files, its too slow ; can't cutomize message alerts and alarm,

it's fake, yes, but its features are not that bad, the MP3 player and Analog TV suits my taste,
as i said earlier, i've been using it for more than a year already, it lasted long enough for me, maybe it depends on your personal handling of the item,

Thank You for reading my post,
