I plugged my phone into iTunes today and got a message in a pop up box. It said something like iPhones memory cannot be detected or is n/a . After I disconnect it from USB and reconnect it the message no longer pops up and brings me to the normal iPhone screen. The last time this happened it showed all my memory usage as other. This time it didn't effect the memory. Does anyone know why this happens and if it should happen again what should I do. Last time I had to restore because the memory problem. Say that happens again, is there another way to fix it besides restoring? any help is appreciated
