Awesome! I now have a working Defy in the Movistar Argentina 3g/H network!
Even though out of the box, the unlocked Defy made in argentina did not work with Movistar Argentina, Froyo + this fix did work. Very weird bug.. but very cool fix!

NOW I'm happy about my defy!

Hey that sounds great and this was the last thing keeping me from upgrading to Froyo. I'm on Australian Telstra network (850) so are you saying I can use either of the US/CN or that last one...do you know which the Au Telstra network is based on or it doesn't matter?

Will wait to hear and then give it a try and report back...

What are the differences between these two?

THX IN ADVANCE.

Question
Hello I live in New Zealand and we have a network here called Telecom XT which uses 3G freq: 850 & 2100 mhz.
Unfortunately all Motorola Defy sold here have their freq specified as: 3G Network: HSDPA 900 / 2100

Does this mean that I can flash the "freq_F_CN_026-850-2100-signed.zip: 850, 2100MHz (ref)" file from OP to the 900/2100 phone and the phone will operate 3G on the 850/2100 freq?

Aittle off topic here but, the vibrant has AT&T 3g and T-Mobile 3g built in. You just have to activate the AT&T 3g radio through the secret settings.

Mentioned this already in the Adlxmod F4D thread but I needed the 3G fix to enable reception of 2G GSM 900 MHz on my Chinese/Asian made Defy. It only detected 1800 MHz networks. I used the Chinese 850/2100 fix for this. The UK 900/2100 fix had no result which means I will probably never be able to receive UMTS on 900 MHz with this phone. Not such a big deal though because as far as I know that frequency is quite rare if used at all somewhere for 3G connections. 2G works fine now but we better rename this thread to 2G/3G fix. Not sure about other 2G frequencies though. Isn't the Defy a quad band?

I've repacked as zip the files that seem to be resposible to gsm/WCDMA frequencies support on the Defy from several dumps (China, Poland, UK, US, all Froyo based). I'm not 100% sure though that it will work, but if it can help.

PLease report your success/failure here :D

Use system recovery to flash the full zip file. It's pretty quick and easy.
