I have a HTC Dream that is unlocked and I am not in the US, currently if my GPRS connection is in active use then calls go to my voicemail. After some research I found that there are 3 modes of operation for a GPRS; NOM1 , NOM2 and NOM3.

Only in NOM (network operation mode) 1 can a GPRS connection be broken to receive a call and it seems as though (through some testing with other handsets on my network) that my carrier is using NOM2.

With that out of the way, does anyone know if the Dream is capable of NOM1?

if you are on a 3G or HSDPA connection then you can be on phone and on the internet. without 3G you will be unable to use both at once
