I upgraded to the 2.2 os. Things have been slow/glitchy off and on since then. My text messaging notifications are now spotty, especially the sound, whereas before they worked great. The worst though, is that I discovered that all my text messaging history appears to have vanished beyond about 10 days ago. Before the update, my history was there from July 15, the day I got my phone. I have lost some very important texts. Does anyone know if there is any way to recover this? I have found messages in the forums about text messages being stored in the contact history even after deletion, but I have checked there and the history only goes back the same length as my text messages now, about 10 days or so. I am very upset about losing the message history for some of my important contacts.
