This is my second international, first with the 2.0 firmware so i'm wondering if something's maybe has changed. I have an unlocked 1g iphone and when I popped in my foreign sim card it worked fine. However I received 2 texts, one from the local carrier and then one from AT&T Free Msg stating that outside US internation voice and data rates apply. Even strange is I received a text from a US friend even though my AT&T sim card is not inserted??

Any ideas? I didn't have this on my first trip and confused as to how I was able to receive a text to my US number.
