Unfortunately, making folders on an iPhone requires iOS 4 or higher. The original iPhone only supports up to iOS 3 software.
From my experience with my iPhone 4, it is in my email box and in trash and in archive.
You can have 16 folders on a page and 12 apps in a folder and 11 pages of folders and 4 folders at the bottom so about 1,980 on the home screen pages after you fill them you can have more and have to search for them
You can't.
What are the Out going settings for email on bell Iphone 4s
You can add a signature to your emails, via the iPhone 4. Go in to the email settings and you have the option to change from the "sent from my iPhone" to anything you want. This will hen be automatically added to all outgoing emails as your signature.
FaceTime (video chat with other iPhone users or Mac OSX users), 5 megapixel camera, HD recording, 16 or 32 GB of space, very fast operating system, folders (can arrange apps in folders by category), multitouch, voice command, front and back camera, and many more
If you mean to block them sending texts to you or calling you, you would have to call up your Network Operator as there is no inbuilt blacklist on the iPhone 4. There is a way if you have your iPhone jailbroken which would be to download iBlacklist but it does cost to download it and I don't recommend jailbreaking.
An iPhone 4 is an iPhone.....
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
If by this you mean what is new about the new operating system, you can create folders, use multiple apps at a time, video chat with FaceTime and Skype, stream music from your Mac or PC, use your iPhone as a personal WiFi hotspot, and much more. (link below
No, they made the iPhone 4 case for a iPhone 4 not a droid.
