Apple - iPhone Cell Phone Review

I am reviewing the iphone by Apple. I have currently had the iphone for more than six months and it works great.  you do not want to download too many programs though, because i am seeing that with more programs or usage of the storage space, the iphone is slower at opening/closing apps.  I got this phone to renew the two year contract and noticed that the phone has come out with the 3GS model.  One of my friend has this upgraded version and says that the newer model is noticeably faster than the previous 3G.  The functions I like the most are the web browser, Google App, maps with tracking function, and also the ability to take pictures and send.  I specially like the fact that the apps are constantly uploaded and updated.  You can choose to download hundreds of softwares for free which is a big plus.  The things I dont like are the fact that they make this scratch prone body.  If makes the phone so much more bulkier because you have to purchase a new case or screen protector.  and without those accessories.. you are going to end up with a phone that is scratch so much.  I never used blackberry and seems like blackberry is the only other phone on the market that has a competition with the iPhone.  I personally think that iPhone can only get better and is much advanced in technological features than any other phone we had access to prior to the release of this phone.  Case makers need to make money too but please change the body on the iPhone Apple...!
