So the new iPhone is en route to my home now -- I have a few questions before I go activating the thing... I had only one rate plan with one phone (Lets identify this as 555-0000) -- the AT&T 450 anytime minutes with 5000 night & weekend minutes. I was not yet able to upgrade to the iPhone @ the $99.00 rate, so I just decided to get a second line. I had AT&T switch my rate plan to a 550 anytime minutes with Unlimited night & weekend family share plan. I ordered the second line (the iPhone), they have already assigned that phone a phone number (Lets ID this one as 555-1111) My question is this: When the iPhone comes in, I want it activated with my original line (555-0000), not the one that is supposedly already assigned according to the AT&T website (555-1111). Can I just switch the SIM cards prior to activation? Will this make the iPhone have the 555-0000 number, and my blackjack have the 555-1111 number? Or... will I need to go into the AT&T store, to have them switch around the account or reassign a SIM card or do whatever? If I have to do the latter, how much does that cost? What should I say to them? As I tried saying above, the only reason why I got the second line, was so that I could get the iPhone at the discounted rate of $99.00. They have already charged my CC with that amount (plus tax). I plan on using the BlackJack as a business line for my small business. Thanks for all the help! If anyone needs clarification, please let me know -- I'll be up all night.
