Wanna unlock iPhone 4 (iOS 4.0.1)

[ViPa]

is ultrasn0w still the best way to go about this? thanks

 

[djvic]

Yes. I believe that is the only way to unlock.

Yes, ultrasnow works on the 4.0.1 i4 baseband.
Assuming you never updated to official 4.1 or 4.2.1
Whats your modem firmware?

1.59.00

You are good then.
You can JB with jailbreakme.com and install ultrasnow from cydia to unlock.
