Following a tumultuous start, it looks like Sprint’s troubles with stocking and delivering BlackBerry Tour units are almost over. A series of three posts from Sprint’s twitter account suggest two shipments from RIM should allow the carrier to catch up with “strong demand”. One shipment apparently arrived this week and a second is scheduled for delivery early next week. Those who still haven’t been able to get their hands on RIM’s latest handset will hopefully accept Sprint’s apologies and sit tight for just a short while longer. We’re still not sure why the Tour was listed as in stock earlier this week when customers received backorder notices immediately after placing orders, but our guess is we’ll never know exactly what went wrong. The bottom line is these two Tour shipments should take care of everyone still waiting to snag a unit.
