Official List of Necessary ExtRom Cabs For Each Carrier

[jimnutt]

Well, for Verizon, technically it's all optional. You can get away without loading any of the ExtRom cabs and your phone will work just fine. You have to set up the data connection manually (using phone number #777 and leave username/password/domain blank, when first connecting and it asks for them again, leave them blank and check the remember box). You also have to set up the voicemail number yourself and the ## numbers don't work, but the phone functions just fine and is completely generic but for the logo on case.
