How do I upgrade my blackberry to OS 5 without a data plan?

[MichaelNguyen]

I don't have a data plan and i'm not subscribe to blackberry. I have a blackberry curve 8520 and I want to upgrade it from OS 4.6 to OS 5

You need a data plan to update your OS.

You don't need a data plan to update it. All you have to do is download blackberry desktop software on your computer.You do need to have internet on your computer.

1-Connect your blackberry to your computer using a USB cable
2-Click "Device",
3-Click "Update"
3-Follow instructions
The software will search for updates. If there are not any updates available at the moment, check again in a week or 2.

You could also update by asking a friend of yours to let you put his or her simcard in your phone and do a wireless update.

Hope this helps!

Install BB Desktop and look for upgrades or updates, connect with data cable.
