As a user of the 2GB data plan, I can say I have never come close to even using 25% of my data because I never download apps over cellular and only watch videos over cellular sparringly an on low 240p quality. I do use Safari regularly, loading dozens of wepages and photos per day, but that does not seem to do any damage at all to my data.
My recommenadtions for you:
Good luck!
You get faster internet then the original iPhone.
does the iphone 3 have to have internet to work.
Not really. For iPhone, you need unlimited internet. That's my opinion. But for some people it may vary. If you are a more browse the internet type of person on a day-to-day basis, then no, 2.5GB of internet is not enough :) Try going into your local phone store and asking the professionals for more details. Hope my answer was helpful!
Yes, it costs extra for the internet on the iphone.
The iPhone has its own Service Plan which has Internet included.
yes, you can just use wifi access to use the Internet on your iPhone
for an iphone there's already an app called safari which is the internet
you can't unless someone stupid enough on ebay or amazon makes you get it cheap
Yes, you can buy international iPhone's version (a iPhone with out Internet) in eBay or amazon, some iPhone that sell outside U.S, is international iPhone' version. You can use it with any network that you like.
iPhone's don't provide their own internet, the internet comes from a service provider so it depends which company a person is with.
Yes it can but, the iphone needs the internet package otherwise your bill will be very high. The iphone is always connected to the internet , and to my knowledge ATT did not allow a customer to have the iphone with out the internet package already in place. Although there has been cases of customers canceling their internet packages and received a bill for a couple of thousands of dollars
You can not download Internet Explorer as a application on the iPhone. You can download Google Chrome insted.
