I looked in the /System/Library/Carrier Bundles/iPhone folder and I couldn't find a MetroPCS bundle. Is it supposed to be stored here or is it placed somewhere else? I am trying to activate iMessage by modifying the carrier bundles using this guide: [Only registered and activated users can see links. ]

I am currently using a Verizon iPhone 4 on 6.1.3 that has been modded for use on MetroPCS via the iPhone CDMA Tool.
