HSDPA Speeds

I have been getting 700 to 900k speeds with HSDPA around the SF Bay area, when I can get that service. Many times, it will unexpected switch to GPRS. I wish there were a way to lock it into 3g when watching MobiTV or doing data centric applications. Or locking to GPRS when you need a reliable phone call!

This has been with the Cingular 8525 / HTC Hermes.

Also, under Phone->Options -> Network. The option to select other networks is now gone. On the 8125, you could manually select other networks.
