You may attempt to load the latest Dev Alpha B update onto your Dev Alpha A, however the Dev Alpha A is no longer officially supported as of 10.1.0.1485.
If you encounter any issues, downgrade to 10.0.10.263 using the Autoloader method. The 10.3 SDK OS (10.3.0.442) is also being made available to those developers who would like to test on their Black Berry 10 device.
Using Black Berry Link, you will be able to reload your device software to a full OS and, if needed, download any OS updates from your carrier.
Restoring i OS 4.1 on i Phone 4 also updates its baseband to 2.10.4 which is NOT unlockable at the moment.

It doesnt, that is in apples firmware only found on real macs.
While in the bootrom state, only a subset of the normal console commands are available. LON 600 server provides the minimal functionality required to troubleshoot and recover its system image.
The FTP server runs, and the console provides commands needed to recover the image; however, application commands, such as listapp and createapp , are not available and certain attributes are not displayed.
Section 3: Appendixes Interrupting the Boot Process The i. LON 600 server displays its normal command-line prompt. LON 600 server repeatedly fails to boot up, you are unable to FTP files to it, or you suspect the image is corrupted, you may interrupt the boot process to troubleshoot the i. To interrupt and bypass the boot process, press the exclamation point (! ’ key to stop auto-boot…” message appears on the console. LON 600 server will reboot to the bootrom state, halting all applications.
If the bootrom file name is different than the default (bootrom.upd), specify the actual file name as an additional parameter.
Update the bootrom by executing the update bootrom command.
The only advantage I see with Boot Camp is a pretty boot loader.
Aside from that a standard Dual Boot will get you going.
