No you will not lose any info stored on the original iphone, as long as you create a back up in iTunes.
When you use the new iPhone be sure to Restore From Backup.
Basically yes. Except taking pictures. :\
Those are apps for ipod, iphone, or ipad for taking pictures and editing them
Yes, it does. This is only for taking pictures using Camera. Using "Lock+Home" to take Snapshots takes PNG images. It also takes MOV videos.
The best tip that can be given for taking good iPhone pictures is to make sure there is plenty of natural light. It doesn't have a flash and doesn't have a high end lens system.
USES: call gps compass texting playing games taking pictures watching videos internet youtube ***and way more uses that are to much to name***
You can switch from AT&T to Sprint if you purchase the software to unlock the phone. As this is not what Apple had in mind you will be taking your chances on not wrecking your phone, but it can be done.
What kind of pictures? Where?
No, taking pictures of a TV will not mess up a camera.
Yes, in fact i just got my iphone 4 few days ago.It's not expensive considering how much the 1st gen of iphone were selling when they first came out. Good functions, great apps(free apps as well), and the camera(front and rear view) is just convenient for self camwhoring and taking pictures.
