I never have a problem with 3G vs. 3.5G with T-Mobile in the US. It's always worked for me.

BTW both 3.5G (HSPA) and 3G (UMTS) are the same technology. There are some speed and latency improvements in HSPA dealing with fast acknowledgements and better data coding, but the backend network is almost exactly the same. So it's quite odd that stuff would work in HSPA but not in UMTS; however as was pointed out if there are a lot of UMTS users hitting the tower at the same time, like a bunch of older phones or users just far enough away to only get UMTS then perhaps those channels could be congested.
