LOS ANGELES � �American Idol� sponsor AT&T says a few overeager company employees helped Arkansas fans vote by text at viewing parties � but didn�t influence the final results.

Kris Allen of Conway, Ark., ended up winning the �Idol� title last week over Adam Lambert, who�d been cast as the frontrunner by the show�s judges.
AT&T said that in the future the company will ensure employees understand that its sponsorship �celebrates the competition, not individual contestants.�
In a separate statement, Fox and the show�s producers said they are certain the results are �fair, accurate and verified� and that the integrity of the voting process was protected against unfair influence.
