I'm in the market for a new phone, but I don't want to leave Verizon. The coverage is too good. I want to be able to root my new phone and load custom ROMs. However, it seems that every phone I research has a locked bootloader on Verizon. Are there any high-end phones that don't have a locked bootloader? Is there any way to buy a phone from another vendor and activate it on Verizon?
