WCDMA Desire

---

I have a desire in Korea running on a WCDMA sim chip on the SK Telecom network. I'm currently in Canada for a while and would like to not have to use roaming. Is it possible to unlock this phone? Are there android 2.2 roms for this phone? If I do this will it disrupt my service with SKT at all? Korea does things a little differently.

I'd head over to the dev forum where you can find a load of unofficial Froyo ROMs.

You can unlock by either paying for an unlock code online and popping that in when using another SIM or flashing the radio which will require root if I'm correct.

Thanks. Whenever I see posts about the desire its always about gsm phones and my sim says its wcdma. Will these roms work?

WCMDA *is* GSM. More correctly WCDMA is a part of the technology used by most GSM networks to implement 3G.

Regard,

You're saying that CDMA is the same as GSM? Huh?

WCDMA and CDMA are not related and completley different.

Dude, you need to go and Google the difference between CDMA and WCDMA or 3G for everyone else out there. Your WCDMA phone is nothing special over the other phones out there

WCDMA uses the same system as gsm (uses interchangeable sim cards) but is used on 3g networks running hsdpa because it was found that the old system (tdma) could not cope with the exponential growth of mobile phones and the fact they will consume more of the network's resources. All WCDMA phones are also equipped with old style gsm radio for when there's no 3g coverage. One worry about roaming to north America is that WCDMA uses different frequencies than the rest of the planet but for straightforward phoning and texting and edge you should fine since the 2g bit of the phone is quad band.

Not exactly true! They are very closely related technologies, but the actual implementations are incompatible.
