Can you take it back to the shop as it's probably still under warranty?
I got a new phone last month, I actually asked in the shop if they minded me playing about with the phones so I could get some idea of how they operate (as opposed to the dummy phones they have on display which give you no idea how it would be to actually use the phone) and I'm smitten
(It's a Blackberry and I love it because I can save reminders and notes on there, plus I have a photograph of my 'I have Aspergers syndrome' card I got from the NAS, so if I ever need to whip that out I've always got it with me and being on my phone it won't get all mangled like the paper version of my card....sorry, I digress!)
Having said that I never could get used to my old Motorola, I used to lose my temper all the time trying to work it, it was a right mess, broken hinge, cracked screen, scratches, I had it for 3 years but I couldn't get it to work with me, it always seemed to have a mind of it's own and the predictive text would 'forget' words I had already entered into it which drove me bonkers!! Some phones have THE oddest operating systems.
