You could put all of their names on a text like you're going to send it to them, then copy the list, put it in a text and send it to yourself. That way when you want to do it you could just pull up the text, copy the names, and paste into the "To:" portion of the text message. That's just the best way I can think of to do it without a 3rd party app.
Thank you this might be the only flaw i see with this cause even with the handscent it dont seem to work as great wish i understood what groups setting is in the contacts, hopefully and update would fix this.
I could of sworn Handcent allowed you to create groups, but I must have been thinking of the batch mode feature. Sorry about that.
There's a bunch of contact group apps in the market you might want to check out. One of them, GroupU claims to integrate perfectly with the default contacts app, and makes it easy to send SMS's to groups.
I'll have to give Handcent a try. I hope it works with GoogleVoice.
Lately I've just saved everyone's text account as an email, and I "text" my group that way. It means I also have their replies in email which is a handy way to save texts, but it's a pain having additional email addresses for everyone...
I also require the functionality of sending mass texts to 20-25 people. And being able to save these groups for future use is crucial too. If anybody finds an app for this, I'd be very interested in knowing. I had a great one for my Pre (Supercontacts).
groups you works great only thing is you have to make sure the number you need to text is saved under mobile cause it dont give you a choice to choose which number to text once you add someone with multiple numbers
