If you only plan on using Sprint as your carrier you did not gain anything in the way of service options. You will NOT use any GSM towers in the US with the Sprint SIM. What you did gain is the ability to flash custom radio ROMs to the device.

By default, the stock Sprint radio only has support for GSM 900/1800 (Euro bands) even though the hardware supports GSM 850/900/1800/1900. When you flash Oli's WU radio to the Sprint TP2 it re-enables support for GSM 850/1900 (NA bands).

The reason that Sprint disabled the (NA bands) is because the Sprint TP2 (unlike the VZW TP2) is SIM unlocked from the factory. The VZW TP2 ships with full band support, but it is SIM locked from the factory.
