I have an HTC Raider/Vivid (Bell Device) and its unlocked and I am using a Telus sim in the device. Just recently I have only been able to download random apps from the market over 3G while others wont work at all. I can download anything over wifi? \
I had the same issue with the Nexus recently and when i did a hard reset on the device it was fine after that.
@lastditcheff: What comes to mind is-That couldBe the SIMcard
the one is causing issues to download apps. Buy an authentic
Bell SIMcard or just for test, borrow a friend's Bell simCard
installed in your phone and try to download one of the
apps that failed, with Ur Telus-SIM card: postBack
