Do all Blackberries from Nextel work with Boostmobile?

I have a Boostmobile unlimited plan and my phone is a Motorola i335. Someone told me that Nextel Blackberries also work with Boost. Is this true?|||Maybe. Boost mobile only guarantees compatibility with the walkie talkie feature on regular Nextel phones. Some Nextel phones use Sprint's CDMA network for voice and data and only use the iden network for the walkie talkie. You will need to contact boost mobile's technical support to see of the Blackberry you want to use will have full functionality.
