I have an unlocked sprint 650 set to work with verizon network, but the firmware in the phone shows 1.03 SPCS software. Phone works fine, but I want to switch it to the now available verizon firmware. I would greatly appreciate some help with this!

Basically, I need to know what steps to take to do this switch without screwing up my phone. Can I just plop the vz firmware into the phone with hotsync, or is there a specific procedure to take?

Thanks in advance for any help guys!
