Hi, Is there a VOIP apps that intergrates with the SMS app so you can have a SMS conversation? I want to be able to send SMSs on pennytel, and recieve SMSs on my number without exiting the app. If tried to write so makes sense, so tell if you don't understand. Cheers. Kinda like this: http://t4show.files.wordpress.com/2008/01/iphone-sms-conversation-out-of-order.jpg but you respond using pennytel's SMS service, or a provider of your choice.
