Possible Solution for PDP authentication failure
I was facing the same problem. Although i still could not put my finger on the problem but I guess it is because of:
1. The iTUNES App store account not set up properly and
2. Phone not synched with ITUNES.
Using below steps helped me:
1. Create a NEW Account using another email id. Use the procedure given below: theappledaily.com/2008/08/04/create-free-itunes-account-without-credit-card/ (Could not post http link here)
NOTE: Follow precisely as mentioned above! One important thing to remember is to keep your country as US - Even if you are in another country, it would not create any trouble. 2. Once you are done creating the id, verify your account from your email.
3. NOW, go to iTUNES on a laptop/Desktop and sync your phone with the itunes.
These 3 steps helped me solve my "PDP authentication failure" problem and now I am able to use my phone everywhere - using service providers internet.
Hope it helps to you.
