Question/Idea about the Sim Card
I am a programmer, but have never messed with unlocking phones. My question however is this.
If you take a IPhone sim card, and put it in an unlocked or AT&T locked phone, it works. but going the other way does not.
So at some level the sim cards are identical. Is it possible that a simple header is being written with a common number? because one iphone card works in another without a problem.
I do not have a SIM Card reader, but If it is as simple as a header, can someone try and read an iphone SIM, and then a regular SIM, and post the header changes? also if you clone an iPhone sim it works.
I guess what I am saying is that if it is a simple header change, then you could do that change to a T-Mobile, or other SIM card, and see if it now works.
Just my $.02 cents and I wish that i had a SIM card reader to try it myself.
If this idea worked, along with the free activation now, then we would be set.
Smartcard / SIM card readers
A few years ago I did a program for a i-cafe to read/write smart cards. When we bought the smart card readers we also saw on sale some SIM card readers/writers from the same company ( www.towitoko.de ).
Just my 2 cents
