Help please! I have a Thunderbolt.. and suddenly I started getting Force close messages on almost every view.. email, text, photos, calendar.. in addition hours later when I tried sending text messages every letter I typed displayed as Q or q. In addition, I have a mac computer. I'm concerned my phone is shutting down and I need to be sure I have securely backed up my calendar and photos. I welcome any and all suggestions. Thank you! Wendy
