it depends on your psp. for example i am using PSP-2000 which i use firmware 4.01 and for my PSP-3000 i am using firmware 5.03.
If the firmware update requires you to pay for it (example: 3.0 or 3.1 firmware), then yes, the iTunes gift card can be used to pay for the firmware.
Firmware is a blend of hardware and software. Computer chips have code embedded on itself to run is firmware. This code would be useless outside the chip and the chip would be rendered useless without the code.
Firmware is the stuff that makes your computer what it is, for example the BIOS is firmware. The computer would be useless without the firmwear. Software is what makes the computer do what you want, such as a word processing program, music program or browser.

firmware is a technical name of computer and its accessories like window is a software and the harddisk that stored on computer is firmware.
Yes, you can The firmware goes across board to all models of PSP. This includes the Customer Firmware and the Original Firmware.
Firmware refers to the system software of a hardware device. Custom firmware takes the place of normal firmware, often adding functionality aspects to the system.
Um, I would suggest to pay someone 20$ for them to put custom firmware. the latest firmware has a lot more functions compared to the 1.50. For example a skype function, a rss function. Internet radio, etc. You are not running any risks, if someone bricks your psp - you can unbrick it, so don't worry.
Softwareis programs which can be installed and used by the user for a specific purpose. Firmware on the other hand is used by the computer system for maintenance and security purposes, an example for thisis Windows Update.
