iphone 3gs itunes sim card error

[Destroybot]

Hi all,

I have an unlocked iphone 3gs, ios 4.2.1. I wanted to add some movies to the phone yesterday to play w/ VLC player. But when I plugged the phone in I got this error:

the sim card inserted in this iphone does not appear to be supported. So I can't access the phone through itunes.

I don't want to upgrade the os or anything, i just want to get some movies onto it for vlc.

Would anyone know how to get around this error?

thanks!

Is your sim card working on your iphone.

Yeah it is, i'm on Tmobile w/ it.

And you are unlocked, correct ? Have you tried close and reopen itunes ? Seems weird...
