For the past 3 weeks or so, I have been receiving text messages late. The strange thing is, it only occurs with one contact in particular, who just so happens to be a person that I text very often. Messages come anywhere from 10 minutes to 12 hours late, and there have been times where they just don't come at all. For example, we had been texting all day yesterday, when she suddenly stopped answering around 3pm. Then, around midnight, I got a text saying "Why haven't you answered me all day?" When I responded saying that I hadn't gotten a text back from her, she replied saying that she had in fact answered my text around 3pm, and had even sent a couple more throughout the day. She also said that she had asked why I hadn't been answering at 7pm... about 5 hours earlier. Which means there were 3 texts that I didn't receive at all, and one that I received 5 hours late.

For what it's worth, I have an LG VX5400 (a dinosaur, I know), and my friend has an iPhone 4S on AT&T. I'm hesitant to say that it is an AT&T to Verizon service problem, because I can text all my other friends that have AT&T just fine. But I'm also hesitant to say that it is a problem with one of our devices, since this problem only starting happening a few weeks ago. Also, I installed a texting app on my iPod, which uses a completely different phone number than my Verizon phone, and I still receive her texts late or not at all while texting from the app.

If anyone has any advice on what the problem might be, or on how to fix it, I would greatly appreciate it.
