Unlock Palm Treo 650 | Phone/Device Issues and Features | Consumer forum

Bought a used Palm Treo that's locked to the Rogers n/w. Has anyone tried unlocking these phones? I'm considering using those online services/websites to get the code to unlock it. There's also a local company here that'll do it (but for double the cost). They say that they have problems with about 1 in 20 of the Treo's not unlocking easily and warned me to stay away from the online places because of that. Is that true or just a scare tactic? Any feedback would be greatly appreciated. Thanks. 🙂
