My phone has caller id blocking on for outgoing calls. For my friends and family that I want to see my number, I store their contacts with a *82 prefix (i.e. *821112223333). I've never had a problem sending SMS messages to any of those contacts before, but it seems with the Droid, I cannot get the default messaging app to send any text messages to my contacts with the *82. I installed Handcent and when I tried to send an SMS, it said "No valid recipient specified". It allowed me to edit the number manually and remove the *82 after which the message sent fine. So that's my workaround for now, but I think these apps should be smart enough to strip that common prefix before trying to send an SMS. Even my previous dumbphones could handle that ok. Anyone else run into this issue?
