This might seem late or irrelevant for the poster, but for other who are having this issue and found this page...

I was having this issue after GB update, I was racking my brains out and then it hit me... pull out the battery and reboot. Not only did my status bar return to normal function, but I also had downloaded an HSUPA patch (non root) which I thought was was not function (I noticed no difference), that now turned into having a minor improvement on my downloading and a major effect on my uploading.

Moral of the story... before seeking drastic measures to quill minor issues, try a minor fix. In all my years of crack and hacking updating and downgrading, this little idea always slaps me in the face. Happy phreaking/hacking/phoning or whatever you are into.
HALO
