Sprint is not a GSM service provider, they use a CDMA network. Also Sprint is now Sprint/Nextel and although Nextel devices do use SIM cards they are not GSM devices either. Nextel uses an iDEN network and their SIM cards can only be used for International Roaming, they cannot be used on GSM networks in the United States. Unlocked Nextel devices cannot be used on a GSM network and unlocked GSM devices cannot be used on the Nextel network as the two are not even remotely compatible.
Sprint coupons can only be used on Sprint products. T-Mobile does not accept any type of Sprint coupons.

This Blackberry is not configurated for use on any other cellular networks including AT&T, T-Mobile, Verizon, etc. On the other hand, a normal Blackberry has no network restrictions and can be used with any cellular network.
Technically speaking, a Cingular phone can be used with T-Mobile, as you only need to switch the SIM card. However, the phone may be locked to Cingular, in which you need to unlock it to be used with another GSM network.
