I am using ZTE Racer aka Dell XCD 28 with MIUI Rom (CM7)..
You will have to install custom recovery, then while powering up press switch on key + volume down key - recover will open, then format everything and flash zip file (the rom). PM me for links I don't know if I am allowed to post.
Flashing custom ROM isn't equivalent to hacking, so you can post the links. But it would be more better if you can post the links of the source instead of direct links. Like, link to the thread on XDA. This way member can judge for themselves if he needs to flash the particular ROM by reading more details of the same.
