Enter *3001#12345#* in your iphone then you will get a new menu. Select Versions. Now you can see firmware version version of your iphone.

if your iphone is having 1.1.1 firmware version then update your phone with iPhone 2.0 and 2.1 firmware version. It will Decrease in call set-up failures and dropped calls and Significantly better battery life for most users.
