Okay, I know I'm idiotic for letting my messages get up so high, but this is my first phone with texting, and beings that it didn't force me to clear the inbox... Well, I didn't, and I have two large threads, once at 900 and one at 1500. How the heck do I delete them? I know HOW to delete, but trying to just makes my phone freeze, in any program I try. Do I have to wipe my phone to make it go away...? Please, any help is much appreciated.
