After accepting a system update, I found that T-Mobile installed TeleNav GPS on my phone. Tech tier support tells me there is no way to remove it since it is installed as a "system level" app or something.
I'd really like to remove it, because it interferes with the default Google Navigation app, coming up no matter how many times I set the defaults.
I planned to root the phone, following the instructions on rootzwiki, but after running Revolutionary I got this message:
Your device: doubleshot, with HBOOT 1.45.0013 is not supported at this time
I've read elsewhere I can unlock my bootloader with software from HTC, but that this will completely format the phone, erasing all personal data, installed apps, and messages.
Do I have any other options to remove this hostile GPS application?
