Anyone else hit by Alltel's wonderful system updates? I received both a letter and several text messages instructing me how to update my phone today. My son tried and has been having a hissy fit because it doesn't work. So did I, minus the hissy fit. If it doesn't work, they then instruct you to contact Alltel Customer Service via landline - because your cell phone no longer works! But I no longer have a landline! So now what? I'd appreciate any help.
