error prompt in messaging then it will fore close then all messages will be deleted

[#1]

HI! I am using Xperia X10 its just 2 weeks old...initially everything was doing great but i had to turn off the settings for the Mobile Networks MMS and data because it automatically connects to my provider and I am being charged and this usually happens when I touch on Timescape. I just dont know if its connected though but after doing so, after sometime my Messaging system prompts me up a message saying that there was an error (android.system.mms) and it needs to fore close and then after that all of my messages were automatically deleted including the message updates in the splines. I already went to the Service Center and the only thing they told me was it will be okay once I have updated to the new version which is the 2.1. Hope somebody can help me on this. Thank you so much.

I've been having the same problem as of late. But it only started happening close to 2 months after getting my phone. It happens more frequent now, and i suspect it's one of the applications I've downloaded. I've uninstalled almost all the apps i've downloaded, removed my battery and memory card. Gonna have to wait to see if it helps. Will let you know
