The BlackBerry Niagara, now called the BlackBerry Tour, is rumored to hit Verizon in July. Pricing is expected to be $199 with a 2 year contract as well.
If this device is going to be announced at WES, it would be a considerable wait from announcement to release. Keep in mind that delays are always expected and mid-July to August is just as likely.
In any case, if you’re on Verizon, get ready for a sweet device launch this summer!
