your HDR AN AUTH Password - is wrong
it should be 8-digit hex form of your ESN
convert your MEID (A00000xxxxxxxx) to ESN(XXXXXXXX)
that will defintly cause authentcation failures
PPP password is alltel
AAA Shared secret: alltel (good)
- HA password should be weird jumbled letter number value, it might be temp value sent to phone when connection is made but i'm not sure on that one, but i know its not alltel
~ personal i'd correct the HDR AN AUTH Password: to your ESN, then power cycle and test

also best mode on alltel for MIP_MODE
is mobile IP prefured
check you modem settings
preferred mode - auto
HDR hybrid preferred - enabled
