I use Handcent for my messaging, whenever i have close to 3000, it makes a new thread with that person. When i try to delete the old thread that has 3000 messages, it will not delete. The phone gets hot and extremely slow and then has to force close the app. It also happened when i tried to delete that thread from the messaging app by HTC. How can i delete the messages without the phone freezing on me. After i attempt to delete and it force closes and i am never able to open any messaging app!!! Therefore i have to factory reset. This has happened 2 times to me.. any suggestions on how i can delete them? Does anyone know where these messages are saved so that i can maybe use Astro to delete them??? Please help... I am tired of having to factory reset.
