My 650 died. I have to replace it. I'm using T-Mobile and I have been using the proxy server option for a long time.

I really don't want to switch from this form factor, but I need something today and I can't get another unlocked 650 as quickly as I need.

As far as I can tell - I'm limited to the Dash and Blackberry.

The Dash seems to be the only option which will allow me to maintain my proxy low cost network needs. Is this indeed true?

Can the Dash handle GPS software and communicate with a Surf3 receiver? I hate to loose my GPS option.

Thanks.
