I just went thru the process of unlocking & jailbreaking my old iphone but need to know if I made a mistake by putting my at&t sim back in it.

If I unlocked my phone with quickpwn then put my at&t sim in it will this in any way "re-lock" it where it will only use at&t? or will it still accept other networks?

I'm askin because after I did the unlock it showed "(null)(null)" for carrier but after I put my sim in, it now shows "at&t 2.6"
If I sell this phone will other carriers work with it?

I know it sounds stupid but this is the first phone I've unlocked & I don't want to fudge it up if someone else winds up with it.

Thanks
