Samsung

I have my phone service through Ntelos, but I purchased the Galaxy II S that was originally issued on the Sprint Network. I had the phone "flashed" and know I can use the phone on the Ntelos Network.

Here's my problem: I can only view streaming video's via Wi Fi. Has anyone experienced this problem? Is there a video application that will fix this issue?

Sprint, Ntelos and the company that flashed the phone were not helpfull.
