Please note that I have a Mobilink Indigo connection. When resetting the "Service Book Entries" and Re-registering the Host names (as suggested on various sites) didn't work out, I finally figured out that I needed to set the APN Name in Options -> Advanced -> TCP Settings to "connect.mobilinkworld.com" without any userid and password. It seems that Mobilink's settings for Jazz are "jazzconnect.mobilinkworld.com". The settings are mentioned on Mobilink's site as well.
Bingo! Everything is back to normal.
