Official List of Necessary ExtRom Cabs For Each Carrier

[nFiniti]

A question about the ExtROMS... When my phone boots from a HARD Reset, when the phone pops up a screen and says in 3 seconds customization will begin, is that the ext rom?

And if so, does it matter at all for any of the cabs inside the ext rom to be there since my phone being an Alltel phone, is flashed to the Cricket Network?

When my phone boots from a hard reset, I ususaly soft reset when that window pops up, just so the things wont install.
