This article explains how to get the HTC Desire Z Working on Rogers
If you need to get your hands on one but aren’t a bell customer, read our guide on that here: How to Get a Desire Z without Being On Bell
We used this site for the unlock code, im sure there are way cheaper codes out there but we wanted it in a hurry. http://www.cellunlock.net/Unlock_Bell_HTC_Desire_Z_p/unlockbelldesirez.htm
After we got it unlocked we followed our old guide on setting up the apn settings for the nexus one – here it is slightly revamed for the Desire Z: Desire Z Rogers APN Settings
Its working absolutely perfectly with full 3G and HSPA support – we have zero complaints with this device, its the best around .. for now.
