I find that PM/Telus's HSPA+4G supporting only 850/1900 3G is too narrow, if they added the 2100 or 2500 as well, then it would ease the pressures on ppl looking for compatible phones, to a certain degree
Also, though awkward to suggest, there are times when I wished the network also had GSM 2G ONLY for the basic service, and if ppl buy ONLY flip phone and only GSM is supported, well, that can throw a monkey in the wrench, matter of speaking
Just my way of trying to help give PM some advice and ideas to help make PM even grander, and ensuring all, even those who only use the flip phones, have all available access to the network, even for the occasional GSM 2G thing and only for the basic of services
