I'm currently on tmobile usa. If I want to unlock a 3g iphone and use yellow snow, will I need to run yellowsnow with a valid AT&T sim card inserted into the 3g iphone? I have an att sim that came with the 2g iphone,that isn't activated. But I have no att sim for the 3g iphone.

Yes but be sure:
*Your baseband must be 02.28.00
*Turn off the 3G switch(coz ure on tmobile usa)
*Sim without pin

I was under the impression that no ATT sim was needed to operate yell0wsnow... has this changed? Don;t you just need the sim you are wishing to use with the unlocked phone?

[dejawoo]

Yes but if you are in usa&using tmobile sim instead of AT&T,you should turn off the 3G switch&try to other things that i wrote.(if you have problems with yellowSnow.Those are advises to solve the issue i said)

As long as an AT&T sim was in there some point of your iphones life, then it should be fine.

And the CORRECT answer is: you don't need an AT&T SIM in at all.

Please don't spread FUD.
