I have both an SMTP and a MobileMe account set up on my iPhone and just noticed that when I send email from the phone, it has a MobileMe return address, not my proper account address. I think it's picking the wrong account, not just wrong email, so is there a way to change the iPhone default email account?

This is just weird. In the last month or so my Apple iPhone has started beeping for an incoming text message multiple times if I don't indicate that I've read it, whereas before it just notified me once and was satisfied with that. Has something evil happened to my iPhone that everything's in triplicate now?

A friend showed me how to use Spotlight search on my new iPhone 4, and it's a great way to find things quickly, but I really, really don't want to have it search the thousands of songs I have on my phone, just my contacts and address book information. Is that something I can tweak or alter?
