My friend just told me something weird about unlock.

He said that the unlock only unlocks it for the sim card currently in the iphone? is that true? cause it sound awfully weird to me
 
Well, kinda. Unlocking a phone allows the phone to use ANY sim card (from any GSM provider), rather than just keeping it locked to AT&T.

From what I recall, the iPhone 3G unlock is a bit different than the normal unlock that most phones get. Yellowsn0w is "a small daemon that is launched on boot. It injects the payload at boot and also whenever there is a baseband reset. You won?t notice anything about it other than that your third-party sim now works. It?s a small program and unobtrusive. There is no GUI (this is by design)." http://blog.iphone-dev.org/pos...11/dont-eat-yellowsn0w

Depending on how you interpret your friends comments, he may be right. Its much more of a grey area than the standard unlock you see on other phones. In a way he is a bit off base (looking at it from the wrong perspective). Its not that it unlocks itself for the sim currently in the phone, its that the phone can only use any sim when the daemon is running, which in turn allows the currently inserted sim to work.

oic. does the same apply to the 2g iphone as well?

No, the 2G can get the regular old unlock.
 
Just so long as we all remember that unlocking is not a magic process that will make the phone work on Verizon.
