Already rare are the people who have an iPhone V1 still alive, except if it is for decoration for collectors.
Then it is true that it is useless to stay on iPhone 1 or 3G, as much to change brand.
All that to say that the 5 comments preceding mine are useless.
Since the iPhone 3G, you have had Christmas (in 1 month it’s Christmas !!) and birthdays.
However, you do have a PC with internet…
Stop believing that only rich people have an iPhone 4 / 4S, I would know if I was rich anyway!
