It goes somewhere beside the power button. It has a mini key or like a metal that you put it in a few cm beside the power button then it opens then you insert the sim card.
You can go to eBay!
It depends on what you like, do you want a keyboard and ping go for the Blackberry, do you want a lot of games and a big screen go for iPhone 3GS
Iphone 3GS- £399.99 (8 GB) Iphone 4 - £499.99 (16GB) Iphone 4 - £599.99 (32 GB) I would go for the Iphone 3GS because it is cheaper and wider screened. But the choice is totally up to you! Good Luck!
yes infact the iphone 3gs does have AIM (aol instant messenger) it works very good and to donwload it all you have to do is go to apps on the phone and type in AIM but usually it will cost no money and sometimes it will but it does tell you. to get an iphone 3gs log onto att.com and type in iphone 3gs in the search bar. and you can chose between 8gb 16 gb and 32gb.
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.
Nope (I quite didn't get what you meant.)
you go to the store and buy an ihone 3gs
The easiest way is to go to the website Jail break me (located in the related links below) on your iPhone itself and it does the work for you.
It is the 4th model of iPhone. But iPhone generations do not go from one up: 1. iPhone 2. iPhone 3G (because of 3G connection) 3. iPhone 3GS 4. iPhone 4. 5. iPhone 4S
Sorry but no, if your on PAY AS YOU GO there is no way you can upgrade. Only the plan users may upgrade.
Yess you can ( but not through the itunes updates). if you are available for an upgrade, just go to the store and you can get the 16GB iPhone for $199, or the 32GB for $299. IF you are NOT available for an upgrade, each is $100 more expensive (16GB-$299 and 32GB-$399). Hope that helped! :)well i dont think you can becuz the iPhone 3G and iPhone 3GS are not the same thing. Most of the time the upgrades are free.. so yeh u cant upgrade a iPHone 3G to iPhone 3GS cuz they are both different phones.
