MMS is working now. it is the order of the steps that messed it up.

i realized i had to do it in this order: load the bunddle, use the tool, and then OTA or manual program the MDN and MIN.

last question:

on some of the iphone 4 (original firmware, without any flashing), you will see a message saying "iPhone is not activated, Ignore or Retry".

after i flash everything, including using the tool to write the data parameter, that error never goes away. i always have to tap "ignore" if that pops up.

that doesn't really affect how i use the phone, but:
1. it is annoying
2. when the phone is in this state, it doesn't show any carrier name or carrier logo (original or the flashed carrier).

i talked to rich before, he said this is the "authentication activation", and the tool should take care that automatically. but even after using the tool, it still has this problem.

any idea?

thanks!
