Looks like the phone number is getting set to 2^31-1, which might
happen if the data type of the column isn't big enough to hold the
value 8888888888 (personally I keep things like phone numbers as
strings - although it's called a 'phone number' it's not really a
number in that things like leading zeroes, punctuation (eg # to select
someone's extension) are often significant).

Please check if there is attr_accessible on your model.
Add :phone on attr_accessible.
