I stand corrected. It simply does not sound correct to my ear, but after reviewing the rules of English, everyone is correct! You do pronounce the -ed at the end of "text." I am just used to correcting my ESL students when pronouncing the -ed in words like work, etc. My apologies!

I'm OK with using "texted" as long as the "ed" is not pronounced when speaking it. As an English teacher it drives me crazy to hear someone pronounce it "text-ted." It's just like the work "worked," you don't pronounce it "work-ted." But as I see it, using texted in writing for the past tense of text is fine.
