They should deff get a 3gs because it has a more clearer screen and it is easier to learn how to use it. I don't think that they need all that the 4 or 4s has... All they would need is a 3gs!! Trust me on this one people over 45 don't need more then a 3gs... Yes, the 4s and 4 has Siri but that is the only difference in all of them... Trust me, I got the 3gs and upgraded to a 4s and hate my 4s!! I loved my 3gs better then my 4s that I have now!!
Yes you should. If you live in the city that is.
Yes, it should work, but you probably will experience some lags considering how old the 3GS is.
Yes, they should be able to. The iPhone is backward compatible. Yes, they can. I used to have an iPhone 3GS and all the games work on my iPhone 4.
I'm assuming this is old as the iPhone has been out awhile, but no there is no return policy with Apple or AT&T.
Not in my opinion
yes
Yes. It can probably be considered old now that Apple no longer sells it on their online Store unless you get it refurbished.
no
It really depends on the kid. If she is extremely responsible than I would get her an iPhone 4S because they are the best iPhone out there and she would appreciate it. Now on the other hand if she is not really responsible than I think you should start her off with a different phone just to see how she handles it. This all my opinion so you should still decide yourself. Like I said it really depends on the kid.
An iPhone 3G cost about $299.00 or $199.00
Stupidest question I have ever heared, ofc the Iphone is better the Blackberry is overpriced old hardware that looks terrible.
No. A 13 year old should have an Iphone Including ones with the letter E at the beginning of their name and an H at the end.
