Samsung Galaxy S-II on T-Mobile.

Available for pre-order October 10th, and in-store on October 12th -- that's two weeks from now.

My phone's been rebooting itself when I'm on the phone and plugging it into the charger, and is just all around sluggish even after a factory reset...and no wonder, considering it's weeks away from being 3 years old.

Why now, why this phone?  It's the first of two new phones on T-Mobile that will run at 42Mbps, with real-world speeds averaging 8Mbps and peaks at 20Mbps.  On a smartphone, that would be faster than either Sprint or AT&T, but half the speed of Verizon's LTE.  If you're lucky and you have a legacy SIM and contract, it means you have no speed throttling or data caps...making T-Mobile's network far more useful than Verizon's, on a value basis.  (One more reason to oppose AT&T's buyout, right?)

Anyway, in the near future Verizon will have a next-generation LTE Samsung Android phone, but until then, the fastest speeds you'll find is on T-Mobile's version of the Galaxy S-II.  Also, both the Samsung and Qualcomm dual core CPUs are ARMv7-based, but apparently the Samsung core has a better built-in GPU, but does not support the higher speed HSPA+ 42Mbps.  This explains why T-Mobile went with Qualcomm's Snapdragon S3 compared to AT&T's choice for Samsung's Exynos.
