I think I have found the fix. Good news and bad news.

Good news it requires no finicking with SSH, carrier settings, or anything else in the IPhone.

Bad news is you need to have another "regular" phone that the t-mobile SIM works in and can access TZones or internet with.

1) Take the T-Mobile SIM and put it in to the "other/regular" phone.
2) Turn it ON, and access Tzones/Internet.
3) Browse around for a while.
4) Remove SIM from "other" phone.
5) Put T-Mobile SIM + Turbo SIM into IPhone (don't forget to turn off 3G).

EDGE turned on right away after I did this.

There must be some sort of "activation" of data access on the SIM that the IPhone with the Turbosim can't do. Hope this helps!
