In what seems to have become a weekly occurrence, OS 188.8.131.52 has been leaked for the BlackBerry Storm 9500 and 9530 (Verizon version). Though it may not materialize as an official software update, is is worth considering - at your own risk, of course. Updates include new copy and paste functionality, full QWERTY keyboard in portrait mode, a change from "Enter" key to "Go" key when browsing the web, and improvements in regards to accelerometer speed.
The last official Verizon Wireless version was 184.108.40.206, and based on rumors received by our tipster, 220.127.116.11 should be coming from Big Red shortly.
