Iphone 3G vs. 3GS

Iphone 3GS and 3G have allot of similiarities. I own the Iphone 3G and a couple members of my family own the Iphone 3G. My phone is different from theres because my phone does not have a video camera and there phone does. Also, there camera is allot better than the one on the Iphone 3G. There phone you can set a picture as the background but on my phone you can only set a picture for when u lock ur phone and not as the background. Iphone 3G can only come in 16 gig and 8 gig but the Iphone 3GS can come in 8, 16 and 32 gig. Also the Iphone 3G doesnt come in white but the Iphone 3GS does come in white. The Iphone 3GS and 3G are exactly the same in looks wise.  Iphone 3GS is worth 549.00$ at telus mobility without a 3 year contract , if you chose to make an account and stay with Telus for 3 years. This means that you have to no matter what conditions stay with telus for 3 years and pay a bill for the phone every month. If you buy the iphone with the contract it is 49.00$ with the contract. Iphone 3G is 9.00$ if you buy it with a 3 year contract. If you chose to not get a contract with the phone and either plan on using it as pay as you go , or do not want to have a contract which sometimes is a problem , you can get the phone for 450.00
