internet 3g semi broken

[htcvogue111]

hi everyone-

I'm wondering whether someone can help me out here.

I had rooted 2.1 before, but upgraded to flipz rom that was based on latest 2.2 leaked sprint rom.

Everything was fine then all of sudden, my 3g started to behave weird---it would work intermittently. I've updated the radio to the latest one. updated wimax radio twice. I even went back to stock rooted 2.2 but to avail---

Did I brick my phone somehow is sprint having some major network issue? How can i fix my issue if this is not related to sprint?
