If T-Mobile says it, it’s pretty much official. The Sidekick Slide (aka the Sidekick Zante) is coming in October, at least to the UK. On T-Mobile UK’s Coming Soon page they have a listing for the Sidekick Slide with “Expected October” listed (along with a confirmation of a 1.3megapixel camera). We find it pretty odd that the UK would get a Sidekick model before the US based on the history of the devices being released. In the past a device has always launched in the US and then trickled out to other markets. Perhaps this is a change in things and T-Mobile is trying out the Slide in the UK market before releasing it in the US. This would definitely explain the lack of FCC documents so far. It looks like maybe the US will be getting the Sidekick LX while others will be getting the Sidekick Slide, at least for the time being.
UPDATE: Looks like T-Mobile has pulled the listing from the Coming Soon page….
