Hello there! Well, you can make a backup of your messages on your memory card without connecting it to a computer. First, go to messaging then, press options then settings then other, you will see the option labeled as 'memory in use' then select memory card when you have it inserted. You will be asked if you want to copy the messages of phone memory to the memory card, select 'yes' then it will take time loading if you have lots of messages. My answer on another discussion that you had posted, it is true that when you have many messages stored in phone memory, it will slow down so it's better to save them on memory card. If you have questions, just post it here. Have a nice day!

that is also one of my questions. i use pc suite. and i can see my folders ( i use folders alwo for my messages. one for each sender )
but the version of pc suite that my niece is using cannot see the folder. although we have the same pc suite version, i think it is in the phone unit? he is using the E series, and i am just using the 7310 supernova.
