5.15.04 /3gs/4.2.1 & Ultrasn0w?

[gadgetmonster]

Curious as I am getting ready to sell a 4.2.1 firmware iphone 3gs with 5.15.04 modem firmware. I'm JB & running ultrasn0w(which installed just fine) but i don't know if its unlocked. I don't want to start the auction saying its unlocked if it isn't. I'm going to try a tmobile sim from a prepaid phone tomorrow or find someone with one I can try but does anyone have any experience with this?

Its not unlocked.
That baseband version cannot be unlocked with ultrasnow.

ok, that was my guess.......there's no other tools that will do it either?

The only way to unlock your phone is to install Ipad baseband onto your phone. However, there are consequences to have this Ipad baseband on your phone. So, read and do some research before you decide to go with this method.

I would do the same.
