1.
Can I keep the same plan if I go to Apple or ATT physical Store to upgrade?
I saw the upgrade Iphone 6S $199 (16G); $299 ( 64G); $399 (128G). Which
one you guys recommend ?
2.
Which credit card to use to upgrade?
a. ATT Universal Card: ATT purchase 5 points per dollar
b. American Express Card: extended warranty ( so 2 years for the phone).
Need your advice. Thank you!
