Unlocking - AudioVox PPC4100 ??

Does anyone have an idea on how to unlock a AudoVox PPC4100 Pocket PC cell phone from AT&T Wireless?

Thanks in advance!

Well, instead you can use Anextek SP230, that is the exact same phone. The only difference is SP230 do not have SIM lock. You can switch to any carrier as long as it is GSM carrier.
