OK this is a little tricky to explain but ill do my best. Let me know if you need more clarification. So i'm looking to buy an Iphone (probably 3gs) and use it more like an Ipod and avoid getting the data charges due to the price. I also have a typical sliding cell phone with a $10 per month common texting plan. Next year i'm going to be on a campus that has wifi throughout the whole campus. So what I need to know is.... Is there an application or something (even if the iPhone needs to be jailbroken) that will allow me to text people through my other phone and receive the text messages that are sent to my other phone to my Iphone so I don't have to carry both around with me when im in a wifi hotspot and will just have all text messages go through my iPhone? Thank You!
