Hi Carol,
Ive already replied to you in another thread, but lets move the discussion to this thread.
My previous reply:
"
Hi Carolina,
What software version is the SX10 running? TC7.x software is not supported. If the SX10 is running CE8 software it should be fine.
In order for me to take a look at this i need some more information. Please go to "About" in the proximity app and find the "Support id". Send an email to me, daneriks at cisco com with the support id. Also please include the a specific time when you had this issue, including what timezone you are in."
