Sprint announced today that LG’s second-gen. Rumor – Rumor² – will be available via Sprint.com (and by phone, what?) as of March 15, with a retail debut following on April 19.

Like the pending (can you hurry up and launch) Palm Pre, the 4.2 ounce Rumor² is exclusive to Sprint (at least initially). The text-centric handset appears to be identical to the previously leaked image we posted a couple weeks back, complete with sliding QWERTY keyboard and extra row of keys.
