Hi everyone. I've been going around with an alternative way to use phone service by my iPod touch 4 for a week. Now, texting (textfree, textnow, textplus, gv mobiles) is ok, making a call seem to be ok with iCall, too. But I didn't find out how to receive a phone call in iPod touch yet, so that my iPod would help me to get rid of the too expensive AT T prepaid plan. Any suggestion. Thank you.
