GSN is an application that alerts you about new e-mails via SMS, directly to your cell phone. GSN uses ICQ for SMS sending so it is completely free.- GSN supports Gmail and POP3. - If you´re connected to ICQ using the same UIN that GSN is using, you´ll get disconnected while GSN is sending SMSes. To solve this issue, you can open another ICQ account for GSN.Note:Requires: Microsoft .NET Framework 2.0.
