I had to have Sprint reset my Optimus s because it froze on some recovery screen and wouldn't even turn off. On that screen it said DO NOT REMOVE THE BATTERY! So I took it to Sprint and they took out my sd card and reset it. That fixed it but ever since I can't open pics sent to me via text message. It says message is expired or not available. My plan has unlimited text and picture messaging. How can I fix this? Do I have to take it back to Sprint and have them reset it again?
