When someone says "I text you", meaning it was something they did in the past, it makes me think that they are trying so hard not to sound illiterate that they sound, well, illiterate.

There is absolutely no doubt in my mind that the proper form of the past tense of "text" is "texted", and that's what I use. My BFF refuses to say "texted", but I think she sounds ignorant when she says, "I text you last night."

Honestly, I think we are just so hung up on what everybody else thinks about us that we've lost touch with common sense!
