Later on, I switched to T-Mobile from AT&T and got an iPhone. Now I want to go back to my SCH-i535. There is only one issue: I broke the sim/sd card reader. Now this lead me to think about a possible way to allow for this phone to be able to be used on gsm networks:
Use the other carriers sim/sd reader.
So instead of replacing it with the standard i535 reader, I'll install T-Mobiles SGH T99 reader.
I want to bring this up to see if anyone already knows the outcome or if they can instantly prove my theory wrong before I buy these things.
All answers are appreciated. Thanks
