You might be forgiven for thinking the HTC Desire Z is the misunderstood second cousin in the HTC litter. When the Taiwanese manufacturer already has the Desire, the Desire HD, the Desire S and more, it’s hard to get your head around just why you should care about the Desire Z. But the Desire Z truly offers something the other models don't -- a physical keyboard.
The economical Desire line keeps chugging along as HTC just announced four new handsets for Taiwan, The Desire 300, Desire 501, Desire 601, and Desire 700. The Desire 700 seems to be an affordable version of the One and it has dual-SIM capability (HSPA and GSM/EDGE).
I have flashed my Desire V using method and ROM from post of "vedang81" in developers section in Desire V forum. My Software is 1.60.707.5 CL69250 release-keys base band 1.05.34D.29_22.214.171.124U. Before rooting the phone my phone was updated to latest HTC updates by using OTA Version Asia WWE (1.60.707.7).
