But *why* did you change your phone ...
my phone history:
1994: Motorola M300 on 1-2-1 that lasted until 1997 when we (MrsJP and I) were given a Nokia (can't recall the model) which had no new features but was smaller with more talk/standby time
I actually revived the M300 for a couple of years when Virgin started - bought a SIM
2001 - moved up to a Philips Savvy. This was because I wanted to have SMS
2005 - moved up to a Sony W800, as I wanted bluetooth, and liked the idea of the walkman
2008 - was given an HTC by work
2009 - was given an N5800 by work
2011 - was given an HTC by work - still my main phone.
From 2005s W800i, the only things that have really been ADDED are 3G and WiFi. Beyond that why do I need a new phone. Sure, I *could* get an iPhone. But it wouldn't really give me anything I haven't got already. My only grumble with the HTC Windows phone is lack of apps, but nothing I actually need.
The next big thing could be 4G, but is it enough ? Especially as most people who might benefit will probably have WiFi enabled phones and a host of hotspots nearby.
