As expected Palm Pre has now been hacked into and made to work on Verizon network, a user with name "cleanser" at PreCentral forum posted a video proof of getting success in making Palm Pre work on Verizon network, the user was able to get Voice and SMS working but still needs to figure out to make data connection work.
It is being expected that "cleanser" will soon release an tutorial on how other users can get this working on their Palm Pre's, once the hack is out other crackers will surely port this to work on other networks providing a fully functional network unlock for Palm Pre.
