Well, there’s nothing official about this yet, but one of the three FCC approvals of the Nokia 5610 Xpress Music, exposes it with the T-Mobile logo stamped on the front panel. Although it is not 100% sure that it will be available, that’s enough to give us hope . T-Mobile is currently offering the 5300 and the 5610 was announced as its successor. By default, 5610 upgrades 5300 with 3G support, but the version with the T-Mobile logo is only 2G quad-band GSM, so it should be considered as its replacement, instead of successor.
