plain Jane 4
Yep. You were able to buy the small sized sim for your iPhone.
I started out in January with a full sized ST sim in a 3GS.
Last week, I trimmed it down to fit an iPhone 4 (not-S) that I've been repairing.
Running 2G and 3G just fine.
All on the AT&T network, so no phone-unlocking required.
I've been approaching the problem one small step at a time, and the only one remaining is MMS.
I don't have that up yet.
But, I'm jailbroken, and so I guess MMS's next. - :up
