Hi Guys . I bought my Itouch 2.2.1 about a year ago . It is acting messed up - I cannot hear my left headphone earpiece . I just checked both of my headphone sets and they are both working fine on a different audio device . I cannot find my recepit to actually see if I got it a year ago and if it is actually covered by warranty . Is there any way to scam Best Buy so I can exchange my old Itouch and get a new one ? I am really desperate. Thanks for the help.
