With any other phone, if an SMS fails to send due to no signal, it stays in the outbox, and is automatically retried when there's a signal again. So why not on Hero? I tried to send a message just now, it failed. When I find a signal... nothing happens. MOREOVER, when I bring up the failed message, and hit SEND, it says "invalid content"... I eventaully worked out this is because it doesn't think I'm re-sending the failed message, it thinks I'm trying to "REPLY" to it with a fresh message. Is there any way to resolve this very basic issue?
