guys can any of you help me?

i can't download any of the free aps from store aps as i do not have a credit card

is there an alternative to this? (i know about installer ap and cydia but they are also not free)

i mean i would like to download facebook aps and stuff but how can i sign up for an apple store account without credit card? does debit card works? im going crazy. just bought my ipod touch 3 days ago and can't do much with it sigh.
