Here is the paragraph you really need to read--->

What about other carriers? Well for the US, Verizon Wireless and At&t will be the two major carriers moving over to LTE 4g technology while T-mobile has not announced their plans and Sprint is using WiMAX. At&t subscribers will undoubtedly be able to purchase an unlocked version of the BlackBerry Thunder (9500 Series) and use it on their network, regardless of the lifetime exclusive agreements between RIM and Verizon Wireless. There is also the possibility that Verizon and Vodafone will not hit their sales quotas and the exclusive lifetime agreement will be void, making the device available to all carriers interested in some touchscreen Blackberry action.
