Hey there people! I live in Canada and I am searching for an App that would allow me to text my friends that lives in US. My plan allows me international texting but my friend's plans doesn't. They are using a normal phones, not Intelligent phones or iPhones, etc. I just want to send them messages(even if it uses my DataPlan(I have 1 GB/month) or my SMS(I have unlimited). I am using an iPhone 4S under iOS 5.0.1. Can you guys help me out? Thanks in advance! Best regards, Drummer.
