Popular gadget reseller Gazelle has reported that it has seen a record-number of Blackberry trade-ins since the iPhone 4S launch. As of last week, Gazelle has seen a 80% increase in Blackberry submissions.

RIM’s e-mail and messaging services underwent serious outages recently, which could also be directly affecting the increased number of Blackberry trade-ins. Android trade-ins also jumped 72% during the past month, with the majority of sales reportedly coming from Sprint customers.

CNET reports:

Gazelle’s “Chief Gadget Officer’ Anthony Scarsella told CNET that this is “easily the highest volume of BlackBerry trades ever seen period.” That includes a “spike” following this month’s outage. “In the grand scheme of BlackBerry growth over the past month, it can be pretty much entirely attributed to the launch of the iPhone 4S,” Scarsella said.
