Little confusing... it says GSM/EDGE 850/900/1800/1900, UMTS1700/2100/AWS, UMTS2100, 1900, 850. For sure EDGE will work on FIDO/ROGERS but it also says UMTS2100, 1900, 850 no AWS.
Where are you getting the info from? If it's on the box, I guess its possible. If it's from GSM Arena
Then likely there are two versions of the phone. The Galaxy Nexus is pentaband and shows like this on GSM Arena
The - hm... - Blackberry Bold, for example, has two versions and shows up like this
Or, one that relates more to your questions, the HTC WildfireS - 2 versions
With the Wildfire, I know for a fact that this is accurate as I actually own a UK one that's the one version but Virgin has one here that runs on 850
The Amaze sold in Canada is one model, all carriers. It supports four HSPA bands: 850, AWS, 1900, 2100.
So yes your Mobi Amaze will work on Fido. Have fun.
I am wondering if this is confirmed as well that it will work on 3G/Fido once unlocked? I am going to be passing a mobi dealer this morning.
I stand corrected - good to know htcs come in multiband.
