Is there any BlackBerry Software through which I can send and receive my texts through a mac desktop?
I have used Blurts with a lot of success on windows.
There is the Cortado line of software. The free version is here. There is a premium version as well. It works by email. So you basically get an email of the txt and you reply to it, once your phone gets it. It will then send the txt out.
I know you can send SMS from your provider's website. You can't receive it since SMS is a protocol that works with NPA/NXX on a mobile device or PSTN.
You can't receive it on your computer if the sms is sent to your blackberry. I have a Storm and the keyboard sucks a hell so I wanted to have the same think you're talking about but it's not possible unfortunatly!
Hope this help!
