If you have a Nokia cell phone you can update your phone yourself without the help of a service technician,You can accomplish this by using a free tool called Phone Software Update
Choose your model online and download the free package that requires your phone is physically plugged in (first time I’ve ever used the cable, thank you Bluetooth) and charging to run. It’s not real clear what’s in the latest firmware, but keeping your gadgets up to date is always a good idea, right? Right? Warning: your phone looks like it’s dying during the 15 minute or so process, but trust the progress bar and press on. It’ll be ok. Oh, and be sure to back up ALL your phone data before proceeding. The Phone Software Update is a free download, Windows only, Nokia phone required
