Various fixes bring 4G back to HTC Sensation 4G after Ice Cream Sandwich update wpes it out


Some HTC Sensation 4G units have lost 4G connectivity
You can't do anything about T-Mobile's change in policy for tethering, but there are a few fixes you can try to regain 4G service on the HTC Sensation 4G. One simple fix requires you to head to network settings and switching to WCDMA/GSM Auto if it isn't already selected. If it is already selected, or doesn't work, you can try disabling mobile networks for a few seconds and then turn them back on. And if that fails to connect your unit with the T-Mobile's 4G HSPA+ network, try toggling to turn on airplane mode and then turning it off.
Right now, there is no word on whether or not this bug will require a software fix from HTC.
