Ok for those having problems try this and see if this works:
1. get a another straight talk phone for cheap! (CDMA)
2.Switch the new straight talk phone to your account(may have to call them idk yet)
3. Do a Factory reset on the fascinate! (if you already flashed good esn to fascinate then skip # 4)
4. Flash the esn from the lg 220(or whatever cdma phone your flashing) to the Fascinate"
5. Bypass activations screen, tap each corner of the screen, starting from the top left corner and go clockwise.
6. Then wait about five minutes, call straight talk, and switch your esn back to the "Straight Talk Fascinate"
5. And then do a *22891 Updated your prl
6. then do a *22890 to program your phone
Eveything should work and let me know if this fixed your problem.
