Hi, I just registered to confirm that I also have this problem. I'm in the UK on O2. Internet connections work in 2G, 2.5G, 3.5G, but not 3G.

I thought I was imagining it at first, and it's been difficult to confirm, as my phone seldom stays on 3G as it usually manages a 3.5G connection. I'm glad others are confirming that this is problem.

Perhaps a way to confirm is to continually ping some address while trying to get it to switch to 3G from 3.5G? I'm not sure if there's a reliable way of doing this.

Unfortunately, I don't have another 3G phone to test if it's my network/SIM rather than the N900.

I'm on the latest version of the OS, by the way (UK edition).
