I think the answer is NO but if I am running 1.1.4 jailbroken ziphone and can I uprade to 2.0 or am I stuck on 1.1.4?

Not knocking 114 I really have had NO issues with it and customize and everything....Im just really wanting the exchange upgrade.


PS. I see there are many more ways to jailbreak other then ziphone, are any of them better? ziphone was great for me
