Show the signal strength
It would be great if you could show the signal strength next to the battery level. For those of us that live in a weak signal area it would be fantastic to be able to see at a glance if I'm in signal before sending a text.
I agree, this would be a invaluable feature to add for this particular reason alone. Another scenario, i use this service when i have my phone docked in my desk drawer at work. being able to see the signal level would be wonderful... it would provide just about the same functionality as the battery level if not more because it could be used to determine if a message didn't send because of the signal.
And going back to the weak signal area, i've lived in that before, where sometimes to get a message out, you basically have to leave your phone in the window sill to get any kind of signal, and being able to see if it actually does before sending... WONDERFUL!
