My phone was working fine in the morning, but now I cant text or receive texts. Ive tried opening the default messaging app, and Handcent SMS, which is what I usually use. But the screen is just black and will eventually pop up with its not responding, sometimes it will open up to the default page, with all your threads, but when I click on one it goes to black. All my other apps work, like internet, phone, and market, but not my messaging ones.
Ive tried turning it off and on, taking out the battery, going to manage applications and clicking force quit, nothing works! Any help would be awesome, thanks.

My phone is not rooted and its a LG Optimus One
