I currently have the 1st Gen. iPhone and am planning on upgrading to the 3G whenever I am able to track one down. I have the 900 minute plan with 1500 text messages and would like to add my girlfriend to my account, also with an iPhone 3G. Will I have to create a family plan or can I just add her to my individual plan for an additional $39.99 (new line + data). I only use half of my minutes as it is so I have plenty to spare. Thanks for the help..
