i have been on my 2g plan using a 3G since last july.... always get messages always ignore them always pay 20 bucks for data 
Just so you know, MMS will not work with a 2G data plan and a 3GS iPhone.Has anybody else besides Spacekitty tired this? What was the result?
I have the 2g iPhone, and its getting old, messing up, and I have no warrenty left. I would like to get the new iPhone 3gS without the extra cost. It doesn't make sense for me to pay $10+ for the 3g service becuase I don't live in a 3g covered area.
When I called AT&T about getting the iPhone 3gS and not paying the 10 bucks extra becuase I have NO 3g service here... she laughed and said... so what, you still have to pay extra... but we are doing our best to get 3g coverage everywhere... you should have it in a year!
*** I was on a pre-order for AT&T dsl; she told me 3 months for service in my area... it only took them 2.5 years!
...so anybody else had a crack at what sweet lil ol' Spacekitty's suggestion?
I've got a buddy that works at a cellphone store that carries various companies such as AT&T. According to him, AT&T - and other cell phone service providers - do a "network sweep," that checks to see the data plan the customer has, and the device using the service. If the two do not match up, AT&T will update the customer to the correct plan so as to meet the device.
If that is the case, then wouldn't my plan be changed automatically by them.
Sorry for the questions, but this is interesting and i'm really not phone-savy.
Not one person has ever been charged extra for using a 3G phone on a 2G data plan.
DON'T get rid of your 2G iPhone. You need it below.
Sure, it's very easy. Go buy a 3G S iPhone at the Apple store. Have them activate it...
Ah, so it all just works out...
Oh. Wait a minute. If no one has ever been charged for using a 3G phone on a 2G plan, why are these precise instructions needed? Why do I have to keep my 2G phone and follow these steps? You just said no on has been charged but then you make it sound like all these steps are necessary.
Which is it?
