A leaked image posted on Tuesday revealed the upcoming release dates for a number of new cell phones coming to wireless provider T-Mobile. While some of the releases range from the relatively unexciting news of a new color option for an entry-level flip phone, the Sony Ericsson TM506 in a scarlet color on January 21st, and the release of Nokia's music-capable clamshell, the 7510, on the same date, they do include much-anticipated handsets such as the Shadow on January 28th.

At the start of February, the 4th to be exact, the carrier's range will be supplanted with Motorola's Renew and Samsung's t119, though no specific information is known about either, with perhaps the former a BlackBerry-like smartphone and the latter an entry-level candybar.

Last but certainly not least, due for a February 18th release, are RIM's BlackBerry Curve 8900 and Samsung's 8MP Memoir, confirming an earlier report. T-Mobile's pricing information for any of these handsets has not been revealed, however. [via BGR]
