A few days ago i plugged in my blackberry 9700 and it came up in desktop manager and mobile internet button showed up on the bottom left of my desktop manager and under tools as an option. There was an update for my phone i updated and rebooted and now when i plug my bb in the screen on the phone will turn black and show it's communicating with my pc then it'll flash and show my background pic then it'll flash and show the black screen again, then it'll flash back to my pic, back and forth a few times before it just shows my background picture. Mobile internet is no longer an option on my desktop manager. I've tried different usb ports and different cables. Any suggestions? I need to tether for work and i don't know why the option isn't even there anymore. It's desktop manager v6 and up to date, my phone is up to date as well.
