Everyday I have been checking the new software download site for AT&T in hopes to find the new os 4.5 for my 8310. Went on as usual this morning to see that they have posted the 4.6 dm software. Seeing that I thought the new os updates would be there. To my disappointment checking for the 8310 still the same old software 4.2. What a tease you are AT&T.
