Can an AT&T Blackjack cell phone be flashed for Boost mobile?

No it cannot.
AT&T and T-Mobile are both GSM (which means they use SIMS cards)
That is why you can use the Blackjack on T-Mobile if you unlock it.

But, Boost Mobile is iDEN, and that uses SIMS cards, but it's a different technology. Only Boost Mobile, and Nextel use the iDEN cards [I'm not sure, but I think the Blackberry Tour can also be unlocked and flashed to Boost/Nextel]

I want to switch from Tmobile to Boost, and I really like the AT&T Blackjack, does anyone know if it can be flashed so I can use it with Boost Mobile?
