Wireless Data

I haven't had any experience with a Motorola and a *.sit file. I acquired this file as a "solution" to the disabled DUN profile via BT. I've scrutinized every bit of the file and it seems legit, I could not find any malicious code.

Question being i'm still rather cautious before loading it up on my phone and wanted to know if anyone has had experiences with this... Success or Failure?

Also, those that have had Success... What would be the best way to load it up on the phone? Not necessarily the easiest, but the most reliable.

Thanks in advance.
