Well I think I text too much for the Hero. For one person, I've hit 5,000 messages, and with everyone else I text, I'm at about 10,000 messages stored in my phone. I guess this is why my phone has been slow to do simple things like change screens, so I'm trying to delete the 5,000 message thread. How ever, when I hit delete thread, the phone acts like I did nothing and I can't tell what it's doing. When I try and delete one message at a time, it force closes. Any idea what I can do?
