iMessage (desktop app) is only for OS X and it's not clear if they'll bring it to Windows. I'd like to send text messages or iMessage texts using my computer. I have an iPhone iOS 5, jailbroken.
I came across this article which allows you to send text messages using the same phone number as your cell phone (this is key) through your computer, but it's only for Android. http://howto.cnet.com/8301-11310_39-57458789-285/send-texts-from-your-computer-with-mightytext/?tag=rb_content;main
Also found this question searching on SU but again only for Android. How do I send SMSes from my computer through an Android phone?
