Plenty of iPhone customers also give 3G by using the device on T-Mobile. There aren't that many of them though compared to the number of people who switched to AT&T (or Verizon) just as there weren't that many people who bought the iPhone 1.

I am one of them. I've got my phone jail broken and on T-Mobile's network so that I don't have to deal with AT&T (unfortunately that is going away).

The EDGE speeds are not half bad actually, when browsing on the iPhone itself they are a tad slow, but over bluetooth to my iPad for example I notice it slightly, but it doesn't really bother me.

iPhone 1 sold pretty phenomenally considering it was a $600 phone, lacked 3G, etc. T-Mobile numbers are going to be dramatically depressed by having to buy unsubsidized and break the carrier lock.
