Sprint Nextel recently revealed that it plans to add Wi-Fi to the BlackBerry Tour starting in 2010, and will begin to require that all its future smartphones come with Wi-Fi. Sprint didn’t say exactly when this requirement will be reflected across its entire line-up of devices, but Wi-Fi is definitely on the way. Verizon Wireless also admitted that it will begin adding Wi-Fi to its BlackBerry line-up in the future, but it didn’t reveal a timeframe. Wi-Fi is absent on devices such as the current 9630 Tour and 9530 Storm.
