Iphone 3G Unlock before selling

[esadb]

Want to sell my iPhone, and was gonna do it locally (kijiji) to prevent scams etc..

The phone is currently locked to Rogers here in Canada. But I was gonna unlock it and then it allows me to broaden the market to Telus or Bell customers.

This is a 3G, 8GB. running 5.13.04 baseband

My question is currently the phone is jbed and running 3.1.3. Whats my better route to go? Restore and unlock while its on 3.1.3 or upgrade to iOS 4 and then Unlock? Can iOS 4.0.1 even be unlocked?

I guess what im gonna have to tell if someone buys it that plans on running it on Telus/Bell that incase the ugprade the fw their gonna lose the unlock correct?

Thanks!

Take it to the local Apple store, ask the genius to upgrade the latest system software saying you don't have access to a computer anymore.

Your guyses replies have nothing to do with my questions.

Yes sure i can unlock it using ultrasnow.

But what about if its on 4.0.1?? Can it still be unlocked?

Also if the FW gets upgraded down the road to lets say to 4.1 DO THEY LOSE THE UNLOCK??

Every time the software is updated, it needs new jailbreaking.
