Some people dont believe that there MP4 is hacked.
There is ACTUAL proof that your MP4 CANNOT go beyond 2GB.
I got a manual with mine, and it prooves that it CANNOT go beyond 2GB.
Heres a little pic;
Now, if you bought a MP4 player over 2GB and got a manual, read it, it will tell you that it can only go up to 2GB. So your MP4 is hacked
Its another way to see if your MP4 is hacked I guess :P
