We've just received a fresh round of release dates on AT&T, and if we had to pick a single word to describe the theme here, it'd be "colors." Shades upon shades of phones -- both new and old -- will see a release on AT&T in the next couple of months, starting with the Sony Ericsson Z750a, the first 3G Sony Ericsson to be released by a carrier in the States (but not in North America -- that honor belongs to Rogers); it'll hit in your choice of gray, pink, or purple in early April. The now-ancient UTStarcom 5700 finally sees release toward the end of April more than a year after we first saw it in the FCC's business, giving a lower-end choice to the Windows Mobile faithful. Finally, May should bring about the LG CU720 Shine in black, following its initial offerings of silver and red.

Oh, and it looks like the Motorola Z9 and the black Centro should be widely available pretty much any minute now -- stay tuned. Strangely missing from the list is the Vu, though that doesn't necessarily mean it won't be released by the end of May, it merely means that AT&T's not sure yet. Surprise, surprise.
