Well, we all know what went down last time T-Mobile held a private launch event in NYC… G1 time. Well guess what folks, a little invitation hit our inboxes earlier today and it looks like T-Mobile has another shindig all lined up for April 21st. Ruh roh! So what do our pals at Tmo have in store this time around? While the upcoming Sidekick LX Blade 2009 etc is fresh on everyone’s minds right now, we’re guessing this is going to be a G2 announcement — sorry Sidekick faithful. We’ll be on hand at the event, live-blogging whatever it is T-Mobile throws our way, but until then… Speculation time. Talk amongst yourselves.
