I recently encountered a problem where I could no longer open my text messages, because a conversation got too long. So I backed up all of my SMS messages to my SD card...and it created a file on my card with no extension. Then I deleted all of my text messages, and texting works again. I guess the phone has a limitation on how long a conversation can be, so once you get too many texts from one person, it no longer let you read the conversation again.
Anyway, I copied the SMS backup file from the SD card to my PC, but it has no file extension, and opening it in any text reader just shows scrambled text. Anyone know what format that the rezound backs SMS files up in, or if there are any PC programs out there capable of reading the saved texts? It's a shame if they are lost forever.
