I think so because two of my cousins have iphones but don't have plans. But i think you'd have to go into the store to get it with out a plan
Sprint has the cheapest iPhone plan right now. You can get an iPhone plan from them right now for only $69.99.
AT&T.
no
Contact the service provider you wish to be with for it to get the plan.
The iPhone is only available for AT&T and yes, there is an iPhone-specific data plan that is required. iPhone's that have been "unlocked" can be used with other carriers such as T-Mobile or Verizon, but even then an extremely large to unlimited data plan would be required (otherwise, you would have a LOT of overage charges since the iPhone is connected to the internet at all times).
You can use the AT&T iPhone coupon code if you plan to purchase an iPhone. You can not use it if you plan to buy another phone.
There is no way around paying for the data plan for the iPhone with AT&T. It is required for the entire duration that there is an iPhone on the account. The iPhone data plan is $15.00/month for the DataPlus 200MB for iPhone or $25.00/month for the DataPro 2GB for iPhone, in addition to your voice plan and other features that you may choose. AT&T frequently runs a sweep of all of its accounts and if it finds an account with an iPhone and the iPhone data plan is not on the account they are adding it, no questions asked.

It is $30
Yes
no
Yes you can but you will not get the benefit of the 3G network speed, you will only get EDGE. Also this will require an iPhone data plan change and if you had the unlimited plan on the iPhone 3Gs you will lose it and you will not be able to get it back.
