My Omnia Pro

‘Mad’ asked (in comments) about the cellular radio setup on the OP.  Here’s what I know so far about the GSM and UMTS setup.

GSM.

The GSM setup is quad band. That’s 900/1800 OR 850/1900 bands. As far as I know, that means it would work on AT&T in the US.

UMTS

The harder question to answer, and the more important one for EU customers, is the UMTS setup. There have been questions about whether it runs HSDPA, HSUPA or HSPA. All the marketing material I’ve seen points to HSDPA. The phone itself also uses ‘HSDPA’ in a number of menu items too.

HSDPA can mean a number of things but it’s most likely to be 3.6mb/s theoretical download speed (as on Samsungs marketing.) As for upload speed I believe the maximum you can can under a true HSDPA (as opposed to HSUPA or HSPA) is 356kbps. It is possible that firmware could improve the download speed to 7.2mbps but it’s rare to be able to upgrade from HSDPA to HSUPA via firmware in my experience.

At the end of the day, 3.6mbps is going to give you 1-1.5mbps under ideal conditions and the phone is likely to be a bottleneck at that speed. Upload speed increases would be nice for streaming video apps and the improves round-trip delay of HSPA would be nice for many apps but I don’t see this HSDPA issues being important to most customers.
