It is expected that HTC Bolt which was to be released via Sprint this month will sell globally with the name HTC 10 Evo which will be the unlocked variant Evan Blass (@eveleaks) has revealed it a tweet.
Last week, the highly rumoured HTC Bolt or HTC 10 Evo was reportedly certified by FCC with the model number 2PYB200. As per the renders leaked last week, the biggest surprise was the omission of 3.5 mm headphone jack and join the likes of Apple, LeEco and Motorola. Nevertheless, removing the 3.5mm headphone jack seems to be a developing trend and it will surely take time until consumers get used to this change. 
Apart from that, the design language seems to have been a lot similar to HTC 10 especially the front. Further, the device is expected to come with 5.5-inch 1080p display. It is likely to have an Octa-Core Qualcomm Snapdragon 810 Processor with Adreno 430 GPU. This CPU and GPU will be coupled with 3GB RAM and 64GB internal storage. The device is also expected to feature HTC’s famous Boom Sound audio technology. 
In the camera department, it is likely to sport an 18-megapixel camera with f/2.0 aperture, 4K video support, dual-LED flash. On the front, it will feature an 8-megapixel shooter. For connectivity, HTC Bolt will feature a USB Type-C port which will also double up as headphones port. Apart from that, it will come with 4G LTE, NFC, Bluetooth, and Wi-Fi 802.11ac etc. The smartphone is also said to running Android 7.0 Nougat out of the box.
So if you were criticising HTC for its Sprint only partnership for HTC Bolt and instead wanted an unlocked version, you might get lucky.
