Earlier today HTC released the source-code to the kernel of the Desire Z. This is great news for the for ROM developers all over since legitimate custom ROMs can now be created and released for the phones.
The kernel is “the central component of most computer operating systems; it is a bridge between applications and the actual data processing done at the hardware level. The kernel’s responsibilities include managing the system’s resources (the communication between hardware and software components).<1> Usually as a basic component of an operating system, a kernel can provide the lowest-level abstraction layer for the resources (especially processors and I/O devices) that application software must control to perform its function. It typically makes these facilities available to application processes through inter-process communication mechanisms and system calls.” (Wikipedia)
Since the Desire Z and the G2 are essentially the same phone, reading between the lines, once we can get past the G2’s draconian anti-customization scheme we could see custom ROMs (CyanogenMod perhaps?) for the G2.
