Can this phone get 3G in Europe on UMTS band 2100? I am still unclear whether T-Mobile's Band IV phones can roam on 3G or not.
If not I hope HTC releases a "world version" soon.

My understanding was that Band IV 2100 and Band I 2100 use separate ranges round about 2100, which is why the Vibrant, for instance, explicitly states that it supports Band I and Band IV.
That is what I thought at first as well.
However the 1700/2100Mhz frequencies of Band IV refer to the UL (uplink) and DL(downlink) frequencies. The uplink and downlink frequencies of Band I are 1900 and 2100Mhz, so I still don't understand really. Perhaps a Band IV phone can only pull down data but can not send any acknowledgments when data is received?
It is all very confusing, wish I could find a clear explanation of what it all means somewhere.
I am still looking for an answer for this, I will be using my phone in the Middle East where most networks use UMTS I 2100 coupled with 1900. On HTC website is not clear, on T mobile webiste they said it's UMTS band IV which is the AWS band and not the European band ( 2100 coupled with 1700) which will not work on UMTS I. I got confused because I read on phonearena that it does support this band ( I). I've just emailed HTC to see if they can confirm.
Dear Raeef ,
Thank you for your response.
Unfortunately, we do not have this information. The information we have is the same as on the website or in the users manual. You will most likely receive EDGE service. You can still send and receive calls, text messages, picture messages, and surf the Internet. However, we cannot specify if the device supports UMTS band 2100.
