got a treo 600 had AT&T for my phone service. droped AT&T and ask that they unlock my phone so i could use my new phone service. they said no. does anyone know how to unlock a treo 600 so i can gain access to a new carrier? i need to be abel to use the phone option rather than buying a second phone.

Same problem here. I bought an unlocked Treo (was originaly ATT locked) foolishly updated with GSM v3.06 AT&T Wireless - and now it is locked again. Need help to unlock. Can I reverse the process ?

I have found the treo 600 unlock code. My mom gave me a treo 600 that she had with service from at&t. I, however was using tmobile. At&t will not unlock their phones for any reason. I found this code online. You can find it too if you go through all the pain and headaches. However, if you want a guaranteed result email me at kagosage@yahoo.com. All I ask is $5 through paypal. Once I receive your payment I will get it to you... I will even contact you by phone if you are hesistant. I ALMOST broke down and spent my money on one of those companies out there wanting to charge $50 - $99. I will give you it for just $5. Email me. kagosage@yahoo.com If it doesn't work I will refund your money. I promise. This feature is completely legal. I researched it. It is the individual phone companies that don't want to give them out for fear of losing a customer to another service. Specifically AT&T for one. kendall
