Not receiving text messages

[ami5000]

It seems that I'm not getting text messages from someone else with a droid x. I'm not sure if any one else is texting me and I'm not receiving them but she has told me that she's texted me and I haven't gotten them.

I'm on a refurb droid x, rooted with gingerbread 4.5.596. Her phone is also running gingerbread but is not rooted.

The last time I received a text message from her was July 22nd which was before I rooted my phone. Between the 22nd and now my phone has been through a factory reset and multiple battery pulls and nothing seems to fix it. I receive text messages from other people without any issue so I'm not sure if it's her phone or mine.

Any ideas?
