If you are nervous about unlocking your device HTC has come up with a safe solution. The HTC Dev program allows you to officially unlock your bootloader without using community-developed tools. On Wednesday, HTC added T-Mobile's myTouch 4G Slide and the EVO View 4G to their long list of unlockable devices.
Unlocking your device may void your warranty, and HTC warns that you should not unlock the bootloader "unless you are confident that you understand the risks involved." Using the HTC unlocking tool involves a five-step process including registration, validation, and email (see picture above). Visit HTCDev.com to get started.
