Oh and CDMA is not going away just yet. If anybody knows how infrastructure works, they dont replace one thing and force everyone onto a new technology just like that. It's gradual, and sometimes it could take atleast 10 years before the CDMA infrastructure becomes obsolete, vendors will stop supporting the equipment, there will be no more patches, no more upgrades, etc. Handsets are already nearing the exaustion point of ESN combinations too, weather you like it or not, thats reality, they did not just decide to switch over for the fun of it, there was a lot of reasons behind this decision. This is when they usually decide to decommission it in flavour of the LTE upgrade path. Same with Rogers, when they went with UMTS 3G with HSPDA technology, they did not abandon GSM just yet. infact, one advantage is of the backwards combatibility and similarities between gsm and umts.
