Blogger Clever Dude reminds us that the telephone excise tax refund applies to cell phones as well as land lines. From the IRS:
You may be one of the nearly 160 million phone customers who can request a refund of the 3% federal excise tax paid on long-distance and bundled phone service billed after Feb. 28, 2003 and before Aug. 1, 2006. Federal long-distance excise taxes paid on cell phone, land line, fax, Internet phone service and bundled service all qualify for the refund.
