Hi all, I apologize if this issue has already been placed but I searched the forum or not I think I read ... I have a blackberry curve 8520 and I want so much to the conversations that I've changed the settings in chat bbm save chat history, and I put on memory card, I realized after 4 or 5 days that were missing 4 days of chat that were deleted from only and do not understand why, and today, for example, which was 6 days were canceled by yourself, it's really strange but I can not understand why ...I have a memory of 4 gb and I have 2gb free so I excluded the fact that it can be a memory problem.
Many thanks to those who respond.
Help me please!:(
