Telus phone with Rogers SIM

Interesting... it should work as from what I understand they both use the same frequencies but not the same technologies (Rogers is using HSPA, Telus I believe is still using CDMA but are in the process of upgrading to HSPA+). Now, the HTC Desire is a new phone so it should work, while according to Wikipedia (http://en.wikipedia.org/wiki/BlackBerry_Storm_2) the Storm 2 you tried didn't have 3G capabilities and that's why you could only connect to an EDGE network.

 

Just make sure the phone is unlocked and compatible with Rogers' frequencies and it should work.

Since I'm not an expert in that field, I'll just give you what my X10a has on the box (it was a Rogers branded phone when I got it)

GSM/GRPS/EDGE 850/900/1800/1900 UMTS/HSPA band 1/2/5/6

If you can get the same info for the Telus HTC phone, see if it's the same.
