Only blacklisted Blackberries are Verizon obviously. Plenty of other cdma BBs you can use. You're obviously not going to be using bis/bes, but you can still get internet and mms. Not going to last long with only 20mb though.

1. Get BB.

2. Change BB Reg ID to 0170 or your SID for your area.

3. Connect to QPST or WS and write prl, msid/mdn, and SID.

4. Go to EVDO tab. Change the PPP/HDR to phone #@vzw3g.com.

5. Both passwords are vzw.

6. Change to simple ip.

7. Load service book through BB Desktop Manager. Alt + SBEB legacy restore mode. Load SB.

8. Done.
