The pot shots between wireless carriers Veizon and AT&T continue with Verizon Wireless on Friday cutting the prices of its unlimited talk and text plans and AT&T immediately following suit. The end result benefits iPhone customers, who can now opt for an unlimited voice and data plan that costs US$30 less per month.

Per Macworld, iPhone users paid US$100 per month for unlimited voice plan plus another US$30 for unlimited data. Starting Monday, however, AT&T is charging US$100 a month for unlimited voice and data. Family Talk plans feature unlimited voice and data for US$180 (assuming two iPhones). Texting prices remain unchanged, at US$20 for unlimited plans and US$30 for Family Talk Plans.

An AT&T spokesman stated that the pricing changes only affect unlimited voice and data plans. Full details as to the new pricing structures can be found here for reference.

For users looking to move over to the new plan, they can make the move starting today without penalty or contract extension using AT&T’s online account management tool.
