There are some rumors that a sequel to the Blackberry Storm will be released in September of this year. According to the source which they say is extremely reliable, the Storm 2 will be WiFi enabled. They also say it will "be an even better Pro-consumer device than the first Storm".
The information is fairly sketchy, as would be expected from the first rumors. If this is a legitimate tip, we should be hearing more in the not to distant future.
