About a week ago, yours truly happened to get his hands on the T-Mobile Slide. The phone itself ran very smooth, which may have well been because it was a brand new phone. The first video is of sub-par quality due to a promise made with the owner, and the second video shows the same phone running Neocore as a demo test. The first test came up with a 33.0 FPS count (with the sound on), but that was not captured on video unfortunately. The second attempt results in the video below.

Here is a picture of the 33 FPS though, along with some various other pictures of the phone:
