The final network to release the BlackBerry Bold 9900 is Three UK. The network release their second BlackBerry 7 device to their list of BlackBerry devices and is available for free on all three of their tariffs. Three UK also have the Bold 9900 available on pay as you go for a low, low price of £399.99. The lowest price I've seen for the BlackBerry Bold 9900 so far. It's even cheaper than the Torch 9810!
If you're on the Three network, get moving now. Here's hoping there's no mistake on that pay as you go price.
