T-Mobile revealed quite a few 4G goodies Tuesday at the CTIA wireless association's annual conference, indicating that it’s not slowing down after the announcement of its proposed merger with AT&T.

Among the several 4G devices the company announced was the Sidekick, a reborn version of the handset T-Mobile quietly retired last month. Boy Genius Report said the phone will be available for $99.99 after rebate with a two-year contract and an unlimited data plan. Without the data plan, it’s $149.99.

The company also made an announcement about its 4G tablet, the G-Slate. The tablet, which runs Android 3.0 Honeycomb, will be available this spring for $529.99 after rebate.

The G2x handset from T-Mobile and Google, which T-Mobile is marketing as a gaming phone, has a 1 GHz dual-core processor and an 8MP rear camera. It will be available sometime later this spring and is the company’s first phone on its 42 Mpbs 4G network.

The company announced this morning that Las Vegas, New York City and Orlando will be the first of its markets to have the network, followed by Chicago, northern New Jersey and parts of the greater New York metro.
