hey JDP:
regarding the stolen phone , blocking the ESN of a phone to prevent usage is ONLY available on CDMA phones. if you lose your WP and they take out the SIM card before your trace it. nothing you can do! I know this cause i got my phone stolen last year
a FOCUS on top of things lol
if your thief doesn't take out the SIM CARD like others say , you can: lock , find , ring , erase your phone.
regarding buying a USED focus.
you can walk into any store an buy it OUT RIGHT , but it HAS to be active ( doesn't need a contract ) the ONLY time you can buy a phone with out activating it is if its a subsidized phone . Subsidized phones are phones sold on non-contracts with out activation.
so you get get the outright price on the phone no contract no problem
BUT!!
i suggest buying it from E-bay or KIJIJI from a local persona and not FULL price cause you will lose $$ for nothing .
+ the NOKIA 900 is coming out in 2-3 weeks!!! your almost better off waiting.
