Regarding the closed thread entitled "I Unlocked My Blackberry 8830
": it should be noted the process for unlocking an 8830 has changed. As the owner of a used 8830 since last September (w/BES service until January) the thread led me to believe concern is due if attempting to unlock the phone; such concern (in light of the experience which was offered) is misplaced.
After calling Verizon to obtain a "Global Phone Support Pack" ($29.99 for a replacement, first is free) a second call to the Verizon Global Support Department resulted in an email message containing the "idemnify and hold harmless" agreement for non-Verizon SIM cards. During the second call live step-by-step instructions for unlocking the phone (i.e. insertion of the Verizon/Vodafone SIM card included with the Global Phone Support Pack as well as MEP2 code and undocumented process for entering the MEP2 code) were provided; needless to say unlocking the 8830 was accomplished with two phone calls to Verizon and at no cost.
