hi, I have a question. I'm planning to get any turbo-sim, and I am still searching. I've heard universil sim is the way to go but it does require sim cutting, and I do not want to cut my sim card at all. Now i know that i-smartphone does not need to require sim cutting at all, and that I should get the black one. Now, i know you can use it without having it to jailbreak it, but the only thing that it won't work is syncying it to itunes.
Now my iPhone 3G is locked to At&t. Say I want to use T-mobile using the turbo sim (which I know it will not sync itunes with that card), now if i take off the t-mobile sim card along with the turbo sim card and just inserting my original AT&T card back into my iPhone 3G, will I have any problems syncing to itunes?
