Best Buy just announced that it will begin presales for the T-Mobile HTC G2 starting Friday. You'll have to plunk down $199 and two years of your contract life, but we're willing to bet more than a few of you will be doing so. Best Buy also announced that the G2 will be available in stores starting Oct. 6. Still no official word from T-Mobile as to when it will have the G2 on sale. [Best Buy] Thanks, Jeff!
