Very weird SMS problem

[gc14]

Here's a very odd glitch I encountered with SMS, maybe one of you guys will know more about it.

It happens when I send a text message and it sends correctly (I get the message sent notification, message goes in my sent messages box etc) and/or I receive a text message from someone else in my text message in box, and the phone locks up shortly after.

I'm not saying the problem is the phone locking up, I'm just saying IF it locks up and I'm forced to soft reset, I found to have text messages missing that I previously had before the freeze. For example, I receive Text Message A in my inbox, and I send Text Message B and it sends fine. I also have old text messages C, D, & E in my inbox, and old sent messages, F, G, and H in my sent messages box. If my phone locks up and I soft reset, Text Message A and B will be gone, like they never existed, while C,D,E,F,G,H will remain intact.

Anyone have ANY idea what's up with that? So far no one on xda has responded so I'm assuming they don't know.

Thanks guys!
