iPhone has weird problems

I can't figure out how to do the following basic functions on my iPhone:

• bcc someone other than me on an email
• add a phone number to my address book while in a call
• copy and paste text
• attach a picture to an existing email
• attach more than one picture to an email

Anyone else sort these out? I suspect they aren't possible, as Apple seems to tolerate odd gaps in functionality in the name of usability.
