Man, these leakers are cutting it close. The T559 Comeback is purportedly launching tomorrow, but it took up until yesterday for the information to really start pouring out – not that we’re complaining. Yesterday morning gave us product shots, but now we’ve got some specs to roll with.

PhoneArena managed to dig up the goods in a document that details the phone in a way only a phone geek could enjoy.

Here’s what we’re looking at:

• 2.0 megapixel camera (with video, though no autofocus)
• AIM, Yahoo, and Gmail email support
• microSD slot expandable up to 16gb
• 850/900/1800/1900 UMTS
• 4.33″x2.20″x0.73
• 4.6 ounces
• Proprietary OS (Booooo!)

As we mentioned yesterday, we wouldn’t expect this thing to set you back very much when it launches on T-Mobile, which ought to be sometime real soon. Anybody else think that keyboard looks incredibly uncomfortable to use? Just looking at that big ol’beast of a D-pad on the right side makes our thumb sore.
