I just bought the coolpad yesterday. rooted it. But every tether app that I've tried never works. can someone out there give me details on what i may need to change/edit in the phone's system folder to enable me to use wifi without metropcs blocking. I know that i had no problems getting foxfi/pdanet to work on my trusty ol' 3g Huawei m835.thanks in advance!!! I really love to use wifi hotspot over usb tethering. but I'll take whatever one that truly works. again, thanks in advance!!!
