According to the latest rumors surrounding the HTC Vision, it looks like the high end HTC smartphone will launch on T-Mobile as a successor to the T-Mobile G1. A new spyshot of the HTC Vision shows T-Mobile branding, but it isn’t known whether it will launch on T-Mobile Europe or T-Mobile USA. If does it indeed launch with T-Mobile, the tipster is reporting it could launch with the name “G1 Blaze” implying it would succeed the G1. In terms of rumored specs, the device should launch with a 3.7 inch WVGA touch screen, 1GHz processor, Android OS, and a full slideout QWERTY keyboard. You may recall the T-Mobile G1 was the first Android smartphone on the T-Mobile network, so it’s no surprise T-Mobile would replace it with a higher-end, more modern smartphone.
