I love my phone and am very attached to it. As well as calls I use it for texting, other messaging (like on Facebook in case that sounds a bit dodgy!!!), Facebook, Twitter, emails, new sites, all sorts of apps and general internet bits, my calendar is on there, I use the alarms and timer. I use the camera a lot too. Notes as well for reminders.
Some of the apps are brilliant. Even got one where some of the buses I get are GPS tracked so I can check when my bus is actually going to turn up in real time, before leaving for the bus stop.
I tend to use old phones as an MP3 player too.
I'd feel lost without it!
