The iPhone 4 does have a removable battery, but it is difficult to take out and not a typical cell phone battery that you can just pop in and out. It is possible to remove the battery from an iphone 4, but not an easy process. It requires you to pretty much disassemble the whole phone.
No, it has built in flash drive memory that is not removable.

Yes, the battery is removable. There's even a longer-running battery made for the Galaxy Nexus too.
The battery that is most suitable as an iPhone cellphone battery replacement is a genuine iPhone battery from Apple. You should not take the risk of damaging your iPhone by purchasing another type of battery.
