The last part of my review is the cool stuff you can do with the iphone. As you might know iphone only comes with some app's. So the first thing you need to do is jail break it so that you can install third party app's. Jail breaking the iphone mostly depends on what firmware you have. Do a Google search and you will get Hundreds of sites that tell you how to do it. Always be careful when you do this stuff, it could brick you iphone.
There are so many fun app's that you will never get bored. I will write about two of them here.
You can play games on the iphone. the nes app is quite playable too. There are other emulators for Gba and psx. But I have not tried them yet. This app gives the iphone the one thing its missing games. And you will have fun playing and remembering the good old times. There are many other games too see some them below. Like solitaire, mine, idigger etc.
Many more games will come to iphone as people realize what a cool gaming device this could be.
You can get others wallpapers with this app lets you see what others people are using as their wallpaper and if you like them you can take theirs and put it on your iphone. It works through gprs so watch out if you don't have unlimited account. But something like this should be available as a default for all the mobile phones. Because changing the background is one of the easiest and simplest ways to customize anything.
There are plenty of new app's coming out everyday.
There are also many web app's which work through the safari browser go here for the list of web app's which work on iphone. But they are not as cool as native app's.
So have fun and enjoy trying them.
Conclusion the iphone is one heck of a phone, there are many nice touches that you will notice once you get the phone. You will realize that this is not just another phone. You will not regret getting it. Even though the price is a bit steep in India, its worth every rupees.
