I am trying to activating my iPhone after replacing the old SIM card with new one. When I connect the iPhone to my PowerBook, the iTune window ask me to answer this:
- I am an existing AT&T wireless customer:
- replace a phone on my account with this iPhone.


- I am a new AT&T wireless customer:
- Activate one iPhone now.

What would be my option?
I am an existing customer but I just had problem using my iPhone. The Apple tech support suggest me to replace SIM card to solve the problem.
Thanks in advance!

1) PowerBook G4/15"/1.67ghz/1.5gb/, Mac OS X (10.4.10), 2) PowerBook G3/Pismo/500mhz/Mac OS X(10.4)
