I haven't posted here in years, but am hoping your collective smarts can help me. I am currently overseas (Canada) and am doing iPhone development work... without an iPhone. I am looking at getting one but they are all locked into certain providers here (Rogers, Fido), and I may return to NZ one day and want to keep using it... My questions are:
1. If I purchase in Canada, then get it unlocked, are their negative consequences? Will push notifications work on any network? Can I update the firmware without fear?
2. I hear that Vodafone NZ sells unlocked phones, if i purchase the device from them, can I use it in Canada / aroung the world on any GSM network without losing Push Notifcations, firmware updates etc?
I would appreciate any advice people have, and apologise if this is a duplicate post or in the wrong section. Also note I am aware of all prices and am more concerned about the technical restrictions.
