thomasina1, I think you need to look at it in a different way.
The iphone is actually a fairly mediocre phone. If you want a good phone, you can get them for a tenner. The battery lasts for DAYS & you can talk on them.
But you can't really surf the web on them. You can't check google maps to see where you are & see realtime traffic (useful just before you go for a long drive).
Nor can you play games like Angry Birds, Cut the rope, Fifa etc. on a normal phone.
Can a normal phone tell you how far you ran, the calories you burned?
Can your normal phone let you watch BBC iplayer, live TV, read the news, update facebook? Notify you when people respond?
Can you sync documents with your phone and take them with you when you travel? Store all your passwords securely encrypted?
If the answer to that is "I'm not really bothered by any of the above" then save yourself some cash & get a normal phone! 
Nokia phones are pants in my opinion. Even their chief exec agrees. Link here
Oops, sorry its a bit of a saga!
