Before you answer “no” have you actually tried it on either an already activated phone or a non-activated iPhone with the 3.0 software (meaning 3GS, out of the box.)
Jolene has a non-3G, non-iPhone SIM that is with AT&T that previously didn’t work in:
– 2G iPhone with 1.x or 2.x software
– 3G iPhone with 2.x software
Tonight on a whim, I popped her non-3G, non-iPhone SIM into my 3G iPhone which has the 3.0 software and it worked. Made calls, received calls, called into VM fine (since it’s not enabled for Visual Voicemail.) I then put her SIM into my 3GS and it worked there too. On a further whim, I put in an old non-connected T-Mobile SIM… the iPhone did not reject it. Obviously I couldn’t place a call but in the past I had gotten a “this is an unauthorized SIM” message. I even went ahead and wiped the 3G iPhone clean and put the SIM in: worked there as well.
And so the questions in my head are:
– Does this only work on purpose or is this a bug in the 3.0 firmware?
– Has anyone activated a 3GS with a non-AT&T SIM?
– If not, does this only work on activated phones?
Or is this breaking news and I was the first guy to stumble into it?
