dear all,
i know there is a lot of threads related this topic but it is the first time to me working with this

i tried with the following,
1- export sms by pc suit from N81 with file .CSV (file name is msg.csv)
2- copy smsimporter and msg.csv to n900 on the root (not in a specifc folder)
3- try to type at X terminal,

chmod +x smsimporter
run-standalone.sh ./smsimporter sms.csv

but i dont know how i can do it,
