Yes, I'm VERY thankful for the unlimited package as well, not for me but for my soon to be 19 year old daughter. It's relatively new to AT&T and her text messaging costs had been a point of contention for some time No worries anymore!
Yeah you're definitely correct on this. In fact, we have 5 phones with AT&T and 3/5 phones will update at least a day before the other 2 phones. It's really weird how it works. So don't just assume you're fine because it can take the system a while to catch up.
Used to when id have my iPhone locked with a pass it would say "Steve Jobs. Text Message" now after 2.1 update it just says "New Text Message" is there a setting that can change this? or is this just something i have to deal with?
