question about upgrading to Inspire 4G

[aparis99]

OK, I have been an iPhone 3Gs user since it came out. I am on a family plan with 3 lines. Mine and 2 Aria's.

I have an upgrade available in 2 months, which I'm hoping they will give me the upgrade by now. I plan on going to the Inspire 4G.

1. Will I be able to keep the unlimited plan? ATT taking that away is/was ridiculous.

2. Does the iPhone 3Gs and Inspire 4G use the same SIM?

2. Theoretically, what if for some weird reason I dont like the Inspire? Could I just pop the SIM back in the iPhone and resume life as normal?

1. Yes, but you might have to call customer service

2. Yes, they use the same sim card

2.(lol) Yes, you can move your sim card back to your iphone 3gs

1. Yes but you have to move to the 4G Version of the unlimited plan
2. Yes it will work but you are better off getting the new 4G SIM that is available if possible.
3. Correct
