Unlocking question

I'm giving my old AT&T iPhone 4 to a friend from Europe so she can use it on T-Mobile while visiting the US. The phone still has my original SIM card. I no longer use this phone since I now have a 5s.

I requested an unlock from AT&T and received an e-mail confirming that it was approved. I have followed all the instructions in the e-mail...

Please allow 24 hours upon receipt of this notification to complete the unlock process.

1. Open iTunes on your Mac or PC and verify that you have Internet connectivity.

2. Ensure the original SIM card that came with this device is inserted in your iPhone.

3. Connect your iPhone using the dock connector to USB cable that came with your iPhone.

4. Backup and restore your iPhone using iTunes. For information on backup and restore, please visit http://support.apple.com/kb/HT1414.

5. After restoring, your iPhone will be unlocked.
After restoring, I erased the phone and went through the setup procedure again. How can I verify that the phone is really unlocked? When I go to Settings > General > About, it says Carrier: AT&T 14.2. Does that mean it is still locked, or is that just a result of it still having the original AT&T SIM card?

Assuming that it really is unlocked, should I now erase the phone again then have my friend put her SIM card into it and set it up for her account?

Sorry, I'm new to this unlocking stuff. :)

Thanks, that's what I thought. But I was expecting some indication in settings menu that the phone is unlocked.

There is no indication on the phone itself whether its unlocked or not.

You can use this http://iphoneimei.info/
to verify unlock, all you need to do is punch in your IMEI and wallah :)

detail you will see :

If you restore it though iTunes, you'll get a window saying it's unlocked right before iTunes asks you to set it up as new or restore from backup. Either that or insert a non-AT&T SIM card.
