Static, yes. But, contrary to popular belief (and contrary to the stickers now being sported at many gas stations), cell phone use is not dangerous when filling up. Most cell phone keypad switches are rubber on top of flexible circuit elements - sealed inside the phone as much as possible to prevent problems with water damage if someone spills things on the keypad. The "spark", if any, that these can possibly cause is generally far enough inside the phone to not have any gasoline fumes present that could ignite. However, for what it is worth, I have stopped using cell phones at gas stations simply to avoid the idiot attendants who instantly bleat out loud angry instructions over the speakers at the pump - right over my conversations!
And, of course, the cellular radio waves do not cause gas explosions (as one gas station attendant once tried to tell me!) I cracked up laughing, handed her my card, and told her that if she was an expert on cellular radio, that she could come by my office and I would interview her for a job that I needed filled!
