If you didn't get insurance on it best bet is craigslist or ebay. Sprint sometimes sells used models in store but the 9930 is really still new for them to have used ones in store.
I just consider them both 9900's no big difference between them and nope i didnt.
Big difference between the 2 considering that the 9930 has 2 different cell radios in it. CDMA which is what Sprint and Verizon uses and GSM for use in other countries. 9900 is GSM only.
