2 questions for binary submission

[vbovio]

Hi fellow devs, 2 questions:

1) on the XCode project target build pane, there is product name, is there a problem if I change it later in an update ?

2) I understand that only i386 and x86_64 are allowed as valid architectures, I tested my binary on the terminal with lipo - info and it only prints these two architectures, so I guess my binary is correct then ?

Thanks for any help!
