No. Nextel SIM cards will not work in T-Mobile or Cingular GSM based BlackBerrys.

Interesting, I didn't know that either.

Nextel is not compatible with GSM (such as Cingular, T-Mobile) or CDMA/TDMA (such as Verizon and Sprint).

Nextel has it's own, proprietary system, which is why it has some cool features like "Bleeping", but also why it has limited coverage since it can't roam on other, non-Nextel networks.
