Mac over at PocketBerry spotted a pre-order BlackBerry Pearl 9100. Generally, pre-release devices will get out to ISVs around 6 weeks before the device actually launches. This gives them enough time to port their software so it will be ready once the device hits the market. That’s about the same time that we start seeing leaks hit the blogs. It’s also around this time that a lot of sites like PureMobile will list the device as available for pre-order, because they might get a few in stock, or they’ll just build up orders for when the device hits the market.
Personally, I wouldn’t go for any of these sites. Just wait until it hits your carrier and you might be able to leverage an upgrade plan to get it cheap.
