I cannot get my Bionic to bluetooth tether in 4g. I have to switch to CDMA only and it will tether. However, my co-worker has a Razr and her phone tethers 4g. Both of us are tethering to a Asus Transformer. Any ideas why Razr allows 4g and Bionic doesn't? I'm tethering by pairing the devices and clicking on connect to the internet. It says it's connected in 4g but the second icon (square light blue with bt symbol) does not show up. It works in 3g though. I've also tried pdanet and pdanet tablet with the same results.
