Hi, I recently got a 3gs updated to 3.1.2 baseband 5.11.07 . I am using this phone on vodafone india prepaid . Initially to access vodafone's GPRS . i created an APN using the iphone cong utilty by following the procedure mention on this link http://broadbandforum.in/vodafone-i...one-india-set-up-internet-gprs-iphone-worked/ initially all was well and i could access the GPRS service but after installing “push fix for youtube ” via cydia , the APN comes up as “unsigned ” and cannot be removed via iphone config utilty as well. i have lost my gprs connection too. can anyone please provide instructions on how to get this “unsigned” APN issue resolved. I also tried unlockit.co.nz to install a new APN but I need to remove this unsigned APN first . the config utilty does not allow me to remove or install a new APN .Can anybody pls give me instructions on how to remove this unsigned APN as I can't find any info on the web .
