You mean, such as this test:

Which concludes that there is interference generated by mobile phones. It also concludes that equipment installed or manufactured before Jul 1984 is particularly suseptible to this interference.
To your point, though, Boeing recognizes that mobile phones have the capacity to cause interference on airline communication / navigation frequencies, but they can not demonstrate a situation where one has actually caused interference:
